Thanks Chris. I downloaded it and it installed fine (which is a start, The other 1 dident install). The thing is, I cant open it. Its in running processors list though. I will restart my PC and edit my post to tell you what happens.
EDIT: Still doesnt sign in. When my PC re-started, My Anti-Virus (Trend Micro) said ''a criticle componment of Windows Live Messenger repaired'' also. Anyone else have any ideas?
