Yeah derekdikbag, that would be my suggestion. I had the same problem with my 60. I called Forat and he actually told me to try that. It worked fine. I ended up getting new ram. It was something about me adding the new software without first removing the extra mem that corrupted it. This may be an isolated case but it couldn't hurt to give it a try....
or give Bruce a call yourself, hes a real cool guy....
