Question, does the computer where you're having the problem has all the windows updates? if is Windows XP do you have Service Pack 3? there are also other set of optional updates that are kind of necesary, they are the Microsoft .NET Framework versions 1.1, 2.0 and 3.0 with their respective services packs? as of late some parts of WLM may need them, Flash Player is up to date too?
