I just tried to play cdlc on my pc that previously worked about a year ago. I can get the game to start and play songs included with the game but when I try to play a downloaded cdlc it won't work. It lets me click on the song but then when I press play it just goes to a screen with the amps on it and stays there. I can hear my guitar but the screen does not change to let me play the song. All these songs previously worked fine but it has been a while since I played them. Is there an update or something else I need to do to get my cdlc to run? Thank you for any help....
