Emu XL-7 & MP-7 User's Group

Hey folks,
              Its great to see such an active group for the command 
stations.  I bought one used on ebay, and it came to me with the 
1.01 OS.  I tried to install 2.0, but am having no luck.  I know I 
had to install the commandprep10 file first, and thats where Im 
having the trouble.  It tells me that its not the right file type or 
something.  I know the connection is fine cause I can download and 
upload patterns.  I also was in the right screen on the mp-7 where 
it says searching for os.  Anybody got any advice for this?  
Thanks.
