I just installed New Veags today and it crashes after the intro so I went looking for the install folder so I could try some fixes but the Steam folder was gone. Searched my whole computer and searched for Civ 5 and L4D along with New Vegas and I couldn't find any installation folders.
So I removed steam with Add/remove software and it removed my 3 games as well which is fine. I then re-installed steam and a folder has shown up. Anyone ever have this problem before?
