@ fire korn Thanks for your answer. RS starts as usual. Official Dlc's can be started. All cdlc's freeze. It does not matter if I start a cdlc's first after starting the game or after I start an official song that was playable. In any case, I have to end the game via the control panel immediately and restart. To turn on the variant beta downloads did not lead to the desired result, as well as the patch.Also a newly added cdlc is frozen "...to verify the integrity of the game..." What do i have to do there?
