After update from 11 SP3 to 12 I see error message while try to run online update.

First I receive message "System already registered", then error

Internal error. Please report a bug report with logs.
Details: Invalid system credentials
Caller: /usr/lib64/ruby/gems/2.1.0/gems/suse-connect-0.2.14/lib/suse/connect/

Where may be a problem? Which logs and whom I must send? My company was bought basic support only...
