Make sure you deleted all your Release 2 files. Make sure you have no RCPADI or
RDPADI or VTPADI or what have you defined in you autoexec. Some may be hanging
over from release 2 and pointing to an old driver. Have you added any, I mean
_any_, hardware when you upgraded to R3? There should be no difference
whatsoever. If something went wrong it is probably something mixed up with
release 2 (old drivers) or some new hardware you added.
