Workaround: in BOINC manager -> choose Add project. (dont know if needed) click on "Einstein@Home" -> in the addressbar put in the new address and click Add. Now choose existing user and put in your known credentials.

Wait for it to update and display your work etc. in BOINC, then go to GR website and delete E@H from your projects.

Last: in BOINC choose Tools and Sync with GR.

not a perfect solution and steps might not be needed, but it has me going.
