cant connect filterblade

hi!

I wanted to make a change to my item filter, so I browsed to filterblade, but was not logged in as usual. When I try to log in, the window with the authorization opens, but when I authorize FB, I get an error message: ERROR 400 ACCOUNT MIGRATION ACTIVE; PLEASE WAIT.

Please tell me that I don't have to wait until monday to get access to my item filters.
