Hi guys. So yesterday I went out and bought a new Hard drive for my computer. Installed my windows 7 RTM, started loading all my programs up...then I ran into Steam. Now here's where my problem is, error message came up around the lines of "Do not run steam in compatibility mode, please turn off any compatibility settings for steam.exe and start again." So I hit cancel to get rid of the warning, and now I can't use steam cloud or find any game info for games that my friends are in. Tried these things so far: Made sure it wasn't on compatibility mode(duh). Deleted the registry key for compatibility settings found here: Fix: Steam thinks its running in compatibility mode. Uninstall and re-install of steam. Finally I went through, turned off UAC and ran it in every compatibility mode possible and switched it off, which finaly fixed it. The issue came back tonight and I just did a reformat, still the same exact thing. Tried everything again as above, still no luck, thinking about going back to Vista 64 bit if this can't get resolved. Specs: Intel Core 2 Quad 2.66Ghz 4GB DDR2 1066 RAM 9800GTX+ WD Caviar Blue 320GB Corsair 650W PSU Windows 7 6.1.7600 Build 7600 Any ideas guys? Thanks!
