said by me1212:@Krisnatharok I could, and probably will. But its the principle. GOG.com's webpage says I can turn my computer off and resume.
It does and I have. I don't know if you are running scripts that are clearing out temp files (a la CCleaner or something) prior to shutdown or what. Good luck with your quest, but the problem is probably your computer, since it did it to both Steam and GOG.
Are you running out of space?
