Hi.
This is a Interet Explorer issue, or if you run Opera or Firefox, pretty much the
same thing, but other way to reset.
I'm running my OS in Norwegian language, so maybe my translate is incorrect, so
try look for similar as I mention here:
Right click Internet Explorer on your desktop or go to Settings in IExplorer menu/
Properties / new box will appear:
Go to Contents / downwards at that tab is a Personal section, click the first button
(Auto...something?) and reset.
This will reset all "memorized" logonnames and passwords set for different websites
etc.
Happy Playing
