Error Codes coming out my ass..
Got errror 81000490?
Well this is the second time I have had this horrible block on the service.
Fortunately it has a quick and easy fix, so all you do is go here:
Close WLM, IE, Everything related to it... and end the WLCOMM.EXE task in the processes,And delete the associated folder with your account, for example:
-You may need to enable HIDDEN FOLDERS to see it...
Once deleted you should be able to log in!
