I had a similar problem a few days ago. If when you type in wgt.com in your browser and it automaticaly signs you in, it is because the "remember me" box is ticked.
So we need to clear all rescent history, if your using firefox try this.
Click "tools" at the top off the page, then click "clear rescent history" then click "clear now".
This will clear your browsing history, Re-boot your computer then sign back in to wgt.com with your same user name and password as before. This should work hopefully. G/L
