Error when uploading end of day - Unknown user[5001]

Please help.

I've been using shiprush fine for like 9 months, then last week, I suddenly started getting an error when running the end of day and the reports won't print:

[TUPS Communicator ReceiveMail] Error receiving UPS Mail List: Mail List transaction failed: Unknown User [5001]

Thanks
