Well, when I open Xbox 360 profile tool/editor I open my account/gamer profile obviously then when I clicked Unlock All (Offline), I get this error: Unhandled exception has occurred in your application. If you click Continue, the application will ignore this error and attempt to continue. If you click Quit, the application will close immediately. Not a valid Win32 FileTime. This is getting quite annoying now, because my 40k gamerscore was all done individually (1 by 1) and my hand is getting tiring.. I even have the latest .NET Framework. It came with this new Vista laptop, I even redownloaded it off the Microsoft Website just to make sure it was all correct and fully working. BUT, theres always a 'but' to something. The good thing about doing it 1 by 1 is because it updates immediately if you sign into your Xbox Account on your console offline, wait a couple minutes and sign into xbox live it'll be there for everyone to see. The downside of Unlocking All is when you do that it takes a while to update. Btw I love the Horizon avatar color changer it's better than doing manually. And I finally got it to work.. Anyway PLEASE HELPPPPPP!
