I've just reformatted my computer with a fresh WinXP installation and updated my drivers, etc. I then installed CK, re-downloaded my Deus Vult purchase from GamersGate, and when I open the DV install folder, the two setup files are showing up as VLC media player (my main video/audio player) files, and I can't open them or the .dat file to actually install the game. Kind of a weird problem, and I can't figure out what I need to do or what I'm missing to run the DV installer, but if anyone has any ideas I'll appreciate it!
