I have CS5 & my Illustrator crashes every time I open it. I had a newer version on my computer for work at one point, which corrupted all of my files & now the program crashes every time I open it even though the newer version is no longer installed. I've tried calling Adobe & I always get stuck on this stupid forum, which gets me nowhere. I need them to give me a new version of adobe illustrator, as I do not want to have to uninstall & reinstall the entire creative suite. To make it more frustrating, I don't have access to my original discs I used to install in the first place & the other programs work fine. This happens to be the program I need the most & this has been going on for years. Very, very frustrating & hindering to my professional development. This was not a cheap investment & I've literally been not able to use it for YEARS!!! I want my money & time back.
