My contractors are stuck at this point as well. They're receiving notices to complete their profiles but then can't log in, repeatedly receiving this error message. 

I've already paid these contractors and am now concerned these payments will complicate future tax filings. This is beyond frustrating when I have hard copies of their W9s and cannot input the information myself. 

How do I rectify this if the contractor is unable to even log into the system to update their W9 information?
