I read a lot of the recent replies, and i could notice that a lot of people is facing the same issue..
I have a lot of CDLC, and I was able to play them all till around September 18th. Then, the game just refused to let me play. I talked to the Ubisoft support, because I was unable to play the songs I purchased. After contacting them for a month or so, all the purchased songs are working! YAY!! But the CDLC leads me to the same amp screen some mentioned before.
Did anyone solve this issue? Any tips?
