The default setting in wincc for op panels is to block users if there have been more than 3 failed logon attempts.
So my guess is that the user is blocked because of too many failed logon attempts and to fix it you eighter have to have some user administration enabled on the op (and to be able to login with administrator rights) or just download the project to the panel again.
YES, i totally forgot about this. I had to resend a program to a customer who locked themselves out a few years back.
