Unsuccessful installation

I purchased aTV Flash 4.4 yesterday for 1st gen Apple TV. Took three attempts to successfully format the flash drive, but still have been unable to install on the Apple TV. I powered down, inserted the flash drive,  but it restarted normally, not recognizing the flash drive. Tried three times with same result. Any suggestions?

Yes, I have the same problem

Me too. Help, please!

Update: tried another flash drive and it works now! :)
