There's no way the client could have deleted all files along with itself; it's just not able to. So either the files were actually still there, or an unrelated third-party program (such as a virus scanner) deleted the files. By the way, in the latest versions it should no longer be necessary to run the game in administrator mode.

Thank you as well. DTA's downloads are hosted by Mod DB's download servers, which are also responsible for hosting files of thousands of other mods, so it's very unlikely that those servers are the cause of your issues. Also, DTA's installer doesn't and can't "use" Firefox. After you've downloaded the installer and run it, it will download the latest files of the mod itself without using any browser. I personally use Firefox and Windows 7 as well by the way and I also use Internet Explorer and Chrome for testing purposes, so I'm pretty sure that neither your browser(s) or your operating system are directly the cause of the issues you're having with DTA (and I suspect you'll most likely have these same issues after downloading other things as well, even if you haven't noticed it yet). Your issues appear to happen while the mod is being downloaded/saved to the hard drive and are most likely caused locally somehow; for example by your internet connection, your hard drive, your registry or possibly even by some kind of malware infection.

It sounds like you're having some unusual issues, since the browser you download it with normally shouldn't make a difference and having to rename the installer after downloading it with Firefox is strange too (what filename did it have before you renamed it by the way?). Possibly your hard drive or partition has errors? If so, it might be worth running CHKDSK some time. To do this, open the start menu, type "cmd" (without the quotes) and press enter. Then type "chkdsk /f" (again without the quotes), press enter and it'll ask you if you'd like to schedule for the volume to be checked the next time the system restarts; now press "y", then enter and restart your computer, after which CHKDSK will start checking your hard drive for errors. Anyhow, to answer your question; DTA does have a map editor included and it's located in the FinalSun folder. Currently there is no support to use multiplayer maps online yet however, but this will also be added in somewhere in spring. If you wish to use a custom map you made in skirmish, you'll either have to manually add it to the MPMaps.ini file that's located in the INI folder (use an existing map as an example to see how to add your own) or if you can't figure out how to do it, you can instead replace an existing map in the \Maps\Default\ directory with your own and then select that map in skirmish in order to play it (mind that the name of the map will then still be the that of the map you replaced if you do it this way). Adding custom maps will also be made easier somewhere in spring. PS: thanks for the welcome, MrFlibble :)

DTA version 1.10 didn't have a launcher yet, so there's no way to update it. The launcher was introduced in DTA version 1.11 and thus only versions 1.11 and 1.12 can be updated. Did you make sure to enter the captcha in reversed order and also to distinguish between upper case and lower case letters? Both DTA's installer/updater and zip packages work perfectly for most people, so I can guarentee you that no files are missing. Just like FunkyFr3sh I'm getting the impression that an anti-virus or firewall might be blocking either DTA itself or DTA's internet connection, so try disabling your virus scanner and/or firewall and see if it works then. If not, try installing DTA to a directory that's not in Program Files; this might help in case you're somehow not getting admin rights after all (right-clicking DTA's launcher and then clicking "Run as administrator" should also help in this case). And if that also doesn't work, try running DTA without the launcher by renaming dta.dat to dta.exe and then running that, but take in mind that you then won't be able to play online, you won't be able to select your starting location in skirmish or select the factions for the AI players and you won't be able to see any map previews. Also, could you tell me what operating system you are currently using?
