Image mode can use a lot of space... more than 2Gb for a DVD. Try profiling without image mode checked.
I've just installed the Game Jackal trial and have tried creating a profile for AoE3 The Asian Dynasties, and I get the same error - "not enough disk space to create the image mode data file". I have several local and network drives, with free space varying from 20.9GB (minimum) to 276GB - more than enough for any profile; but image mode isn't chcked anyway. I can't find anything in settings that allows me to set a location for the image mode data file.
Any ideas? My version is up to date, I'm trying to create the profile by dragging the game icon to GJ. The error occurs when I exit the game. I'm running Vista Premium.
Thanks
