Authentication server error, patch error code -47 and margin server error

I get one of the errors listed in the subject line every time I try to log on.  Most of the time it's the patch error, second place is authentication error, and i only got it to let me log in once for the margin server error.  I played this morning just fine, now it's gone crazy.

Try re-patching and if that failes try re-patching again with anti-virus softwere off. good luck
