I get an error message that says "Can not authenticate you" when I try to buy lindens.  I also can not buy from marketplace...when i click checkout the next screen is blank white and does not go anywhere.  Then I can not go forward or back.  I also tried to buy something inworld and it says failed because there is not enough lindens in the account when there were plenty.  I tried logging into another account and everything worked fine.
