Illegal exception
---------------------------
An exception 0xC0000005 occurred in ACWIN.EXE at EIP = 0x004140CC ; program pointer is +3330, ACI version 3.21.1115, gtags (0,0)

^I've been getting this recently. I can run the editor, compile the game, but whenever I try to run it in the editor, it refuses to work. For some odd reason, I have all of the program files on my desktop, and when I sent some of those to recycling, it refused to work. When I restored them, however, it worked. Now, I put some of them in recycling this evening after getting new virtual desktops. Much to my chagrin, nothing works now. I've got all the files out from recycling, but it won't run in editor. Also, I tried downloading AGS again to see if I could run a different one for blah blah blah, you get it. However, I can't even open that one. Should I permanently erase AGS (And save my template/games elsewhere) and redownload or can I fix this?
