I play the CDLC song(PC) and at random points the page shrinks down and song stops.  I typically have to click on the rocksmith pin on the task bar twice to get to open back up then have to hit resume.  I have tried taking programs off my computer running in the background but that doesn't seem to be the issue.  There is a box in the background that typically says something about patch verify success, but I'm not sure thats related either?  any solutions??  thanks
