A late reply, but I just encountered the same issue when I was try to soft link the cache and files folder to my external SD Card and I screwed something up. I even deleted the APK, the Dexed Application, and the data folder with the cache, database, etc. Interestingly enough, when I did a full re-install, I still had the same issue! I did two things, not sure which one of them fixed it (or both) as I didn't check in between. Under Preference, I turned off all caching and turned on stream via WI- only. My guess is that really did not do anything to fix the problem, but like I said, I don't think I checked the operation after that. What else I did was log into the Music Manager on my PC and deauthorized my phone (device) that was having the issue, and viola, it now works and streams, etc. , even though it is deauthorized. Hope this helps someone as there were not too many posts about this issue and no replies.
