Machine won't start

I unplugged my Tajima TMEX C1501 for about two months for shop updating. Now when I turn it on the machine keeps beeping and the screen does not work - the little green light is on, but none of the buttons work. I tried to put in the original disk but it won't load.
Help!:confused:

my TMEX C1501 is showing 211 error - I don't know how to fix it. Help!

I called Hirsch and the tech had me reset the machine using the original setup disk! it now works!! yea.
