I'm having some Dune EX problem regarding crashes, and file extension problems. Whenever I try and open Dune EX, the program crashes and doesn't ever display/prompt. These are of course regarding to the file extension: .RFH. I have tried re-installing many times, restarting my computer & then re-installing, deleting all files/traces of the program after un-installation, etc. I have read the readme.txt file left by the creator, but there was no useful information found in the document. I need help! I can't access the .RFH files!
