Error 412

Error 412

I have been unable to link bank since i subscribed.  Every time I try to link to PNC I get "error 412."    When is this going to be resolved.  Linking worked in the trial period and when I paid for my subscription, the link to the bank and the bank feeds will not work.  Is there any work around for this other than entering everything manually??  I have been told by their helpdesk for two months it is being worked on but still not addressed.
