LAST.FM Crashes my ATV2

I was able to JB and installed aTV Flash Black without any hiccups but when I try to install LAST.FM app from NitoTV I always get a blank screen after the installation completes and can't do any thing else from there, unplug, re-plug tether rebooted and nothing but a blank screen; anyone else having this issue? How can be fixed? is only available through the Manage Extras menu under there something else you're installing via nitoTV?
