it looks like there is a problem with my Username.
At Registration "RT1984" was used, which is also showed on the right side of sreen next to "logout".
But on the left side and at BOINC its "old_user37638".
User-ID is 37638

To comply with data protection regulations, old accounts have been processed to remove references to e-mail addresses (see here). The account you mention has not processed any models in ten years, until the recent attempt on 30 October 2017, which is why the account was renamed and the e-mail references removed.
New models can be processed under your new account. If you need access to the old account for some reason, I can investigate how that might be done.
