It's a torrent that's more than a year old, what do you expect? That said, here's a working torrent instead: girlcelly's alternate upload on the Nyaa tracker.
Could you please re-upload;
"[2010][FLAT] Utatemeguri(うたてめぐり) [Soundtrack CD + Special Song CD + Update 1.1]" ?
Quite sorry, but RG doesn't work for me.
