"undefined external error" states it is an external error."
Meaning PT has an issue communicating with some other item/device (external)
What are your Audio device settings?
What is the MIDI device?
Are they selected in Options - Preferences ?
This is PT telling you "hey, I can't find/talk to something .." (usually)
