So, I did get the CDLC to work. It seems that I had some bad luck with choosing songs. Once I repackaged them, they worked. Although, I find it difficult to believe that four random songs all had packaging problems, but that's what got them to work. Weird, huh?
Lance, did you ever find a solution? I've been using RS2014 since December 2013 with no problems. I used CDLC without problems for about the last year and now I'm having the same exact problem you are experiencing. The only change to my computer is that I upgraded to Windows 10, but I don't think that is the issue as I've tried it in compatibility mode and that didn't help. Thanks for any help you can provide.
