Bc2000 (for the BCF2000 & BCR2000)

Hello everyone, 
i´m new here, and first of all, please excuse my englisch, it´s not my native language.
I got my BCR2000 used, and i´m new to that MIDI stuff, but i keep trying. 
Here´s my Problem: i wanted to upgrade the firmware from 1.04 to 1.10 using BC manager, and there were some dificulties resulting in my BCR showing "noOS". I already read somewhere here, that this is worst to happen, and i should read "BC MIDI Implementation.pdf" for help but i wasn´t able to find this file anywhere. After trying uploading the firmware again, there was a prompt saying: "no driver" or something like that. Trying to install a new driver failed too with the words: "This version of Windows is NOT supported! PLEASE CLOSE APPLICATION". 
This Device is frustrating. Really. What am i supposed to do now? I need help. 

thx
