I have exactly the same problem - also took the first copy back (to "Game" in the UK where it was bought, where they exchanged it without hassle) and the second copy does the same. I have an HP Pavilion ZD8227 laptop running XP Home SP2, P4 3GHz, ATI Mobility Radeon X600 (128M) graphics builtin and TSSTcorp TS-L532M combination DVD-RW / CD drive. I've tried multiple times to install and launch the game, even tried deinstalling and checking for leftover registry entries (didn't find any - and I DID see them when I went in after re-installing). No dice. This is a serious PITA - if I don't get it sorted I'll be taking the game back to the store (they said they'd give a credit note if I couldn't find a solution). A google search suggested that this problem also occurred with "Hidden and Dangerous 2" but the links to the forums of course don't work, because the forums are gone from the Gathering site now :( From what I could see in the google search returns, I think there was talk of a registry fix to correct the expected CD-ROM ID for the PLAY disc, is there anything similar for RRT3? I really WOULD like to be able to play this. Thanks for any suggestions...
