I have upgraded to 2.08 it still works, I was able to track down 2.00 firmware looks like you can load it back I have not tried it because I haven't needed too, unfortunately it almost seems like 3d systems monitors the internet and removes information about there company/products I couldn't find anything about troubleshooting or common problems with them. Honestly I am a business grad I can understand why they would want to lock down everything and make it unmod-able. I'm happy with it if it works but I have already found out a few things that I will probably eventually sell it and upgrade to a 2 or 3 color printer with a heated bed and a bigger print area 12x12 would be a lot nicer.
