I have upgraded the system, but lost all the styles. I think the problem was lack of memory, even though I checked before starting.
I believe Wis was right, I copied the entire folders instead of the contents and now the available memory isn't large enough. The instructions didn't spell that out.
Roland does have instructions for updating from the external memory. I tried that only after having problems, and it worked fine, but had the same problems.
When I get time later today, I will have to re-format the internal memory and start over.
At least the OTS works right now!
Thanks for the help,
