aTV will not boot

I just purchased and installed aTV flash about 2 weeks ago. Upgraded aTV to 3 and flash to 4.03 I believe.

Seemed to work well at first, but then started acting more and more buggy. Sluggish and crashing or needing to restart. Today I could not even finish watching a tv show, the atv froze three times.

I upgraded the software to flash 4.04 but problem persisted.

Tried to restore to the original software, but now it does not boot. The amber light flashes for awhile, then just stops.

What can I do?
