I've been using CDLC fine forever now until a recent and totally aggravating quirk. Before I describe what's happening, I've done all the common fixes. Verified game integrity, removed every CDLC, even reinstalled from scratch. I start Steam, then run RSInjector. Here's what happens: When I have an active internet connection, most of the CDLC songs in my list are shown with no cover art. When I try playing those songs, RS crashes (it doesn't even get to the tuning). When I turn off my internet connection (after Steam has loaded), there are no more songs with missing cover art - in fact, the songs that previously had no cover art aren't even in the list. Here's what I know: RS talks to Ubisoft servers for each CDLC song. For some reasons, some songs are "blessed" by Ubisoft, some are not. I haven't found the pattern yet. I have logged packets, but it's all over UDP, and all the data is raw binary. It'd take some time to start breaking it down. So before I start digging in, are any other Mac users seeing the same thing?
