Yep, hotfix doesn't seem so hot, sync has stopped at 20160 blocks for 15 mins now and doesn't look like it wants to move on.
I'm getting a similar problem, syncing isn't going pass 20660 for me (27.73% done). On another note, the client version is still showing v2.0.0.0 for me. Are you sure you uploaded the hotfix v2.0.1.0?
