Is your partition named "CDH0"? or maybe the link should be DH0. Check in WB if the files are there, check your assings in s:user-startup, make sure it points in the right folder. Ther is a icon in Toaster folder to "Check Software", when you click on that, it will verify if all files are there. Mine had 2 errors, but it still worked.
If that doesn't work, just reinstall the sw.
I was just messing with my Toaster 2000 last week, so I'm kinda fresh.
