haven't heard of anyone having problems with any of the miditxt files, penny - so I would say just replace them by downloading again. you can go to the link at any of the threads that has miditxt.*I* had 7 out of ten machines in a lab crash last week - all the same age, all died within 3 weeks. (two the week before plus one this week)
It's just the 'possum in the 'puter.
