Im in the same boat. I downloaded an image of the software and another version with "extras" but the instructions are horrible.
This is driving me nuts. I have read, re-read and read again.
Damn you ADD for clouding my thoughts.......
If anybody would PM me on this matter, I would very much appreciate it!
