Sorry, guys. I solved the problem. When you are going to update ms609 don't use the MaxLink 1 update program wich came in the CD. Use the newone inside the update kit (Maxlink2). It is been sad in the Updata instructions for MS609.pdf, although I didn't imagine that the update program MAxLink 1 would be the problem. Doing that, your scanner starts to work. I hope this helps everyone else. My mail is duanedan@gmail.com and I would be glad to help.
