Hey Guys, sorry I have not been able to reply. I did just send someone the firmware, so I hope that helps.

If anyone else still needs it, here is the last stable version. This is what most, including myself, are running.
TerraMiner_0.7.56.tgz 11.4 MB

If you are having problems with the miner not doing anything from the web interface, make sure its connected to the internet first. If it cannot connect, it will not work at all. Past that, crack it open and go USB right into the miner (CTA) and use cgminer to try and wake it up. You can also do a firmware update/rollback and see if that changes anything. However, you should be able to run it right from a PC with no issues if the hardware works. I just had one of mine start to die and it is the cooling system. Something actually broke inside of it (the pump) and clogged up the line so it was heating up and turning off. I whacked the line out of the pump and could feel objects moving through the line, not good. However, it is running again so there is hope. If overheating is your issue, dont be afraid to smack the pump a little while its running to see if you can get it flowing again. That has worked for me on several occasions.

Good luck!
