Greetings, Great site, and sorry for wanting help so quickly lol, but needs must as im getting brain dead from trying to fix this on my own. I have recently upgraded to Windows 7 ( OS Name Microsoft Windows 7 Ultimate Version 6.1.7600 Build 7600 ) I ran the compatability test before i installed it and removed all noted programs. I have managed to transfer all the data back from Vista ok, emails, contacts etc, with the exception of Windows live messenger not logging in. I checked the error code 80048820 and found it was something to do with the timezone clock. I notice it is set to UTC, and i am GMT, i do not have any options under the windows 7 options to change this as UTC is the only time zone option listed there. I dont know how this has happened, i did not get the opprtunity to set the time zones when it was doing the install / upgrade, i assumed it would simply copy from my vista ultimate install. Has anyone get any ideas, before i start to wither away and go bald from ripping my hair out Thanks in advance.
