Logic Pro has detected a MIDI timeout error

All of a sudden I am not able to launch Logic on my MAC BOOK Pro machine. I keep getting an error message with MIDI timeout.
MIDI timeout
Logic Pro has detected a MIDI timeout. Please restart
your computer, then relaunch Logic Pro.
If the problem persists, update the drivers of all
Connected MIDI devices (including audio drivers with
MIDI functionality) to the latest version. For
Instructions on removing older drivers, consult the
Manufacturers’ documentation.
OK
I have restarted my machine a couple of times and the error seems to continue to exist. It displays as if it is going to launch, but when it comes to starting the MIDI driver it just stops.
Thanks in advance for any help.
