I did not have any errors getting the database using 1.53. I’m sure you did this, but double check that your MIDI I/O is properly configured inside 1.53, and delete the library I included (unless your 4000 is version 2.158). If it works in a newer version, there is no reason it shouldn’t work in 1.53.
Does your 4000 show any signs of receiving MIDI from 1.53?
