I have recently bought a POD Studio UX2, but it keeps shutting down all of a sudden!

And the only way to turn it on again is to restart the computer.. but then, when I start using it again, and the same problem happens after a while..!

I am really frustrated, I wasn't able to record or create new tones, cause I can't go more than half an hour without it shutting down!!

Can anybody help me please??!

Note: I own a Mac with the latest version of Mountain Lion.

All of my Line 6 softwares are up to date, according to Line 6 Monkey.

Thanks!
