Are you seeing an Escaped_Chasm_Contents folder with Escaped Chasm and Extras folders in it? There should be an executable named "Game"/"Game.exe" in the Escaped Chasm folder and, if there isn't any, it might have gotten removed by an antivirus.
I am, but the Game.exe is only there before the files get extracted.. darn, that sucks. Was hoping to play it before watching anyone else.
Thank you for answering! :) not having an idea as to what was going was killing me
Do you run any antivirus programs and could you check whether they quarantined the Game.exe file? That's the usual problem behind files not appearing after being extracted from the archive.
