I made a gamedisk to send it to a friend to test some things out. Afterwards, my entire project folder is gone. My project seems to be deleted. What the hell happened? I don't want a weeks work to be gone just like that!

Ah shit never mind. God damn I thought I lost the game. What happened was that I made a gamedisk and then installed it onto my computer. I then uninstalled it afterwards. If my friend deleted the project, right now I would be royally screwed. Thank god she still had it.

'dem uninstallers are fast.
