I cannot speak to DB200 -- I am too chicken.? But I have had a few cases where programs have gotten corrupted in weird ways.?? You might try replacing your processor with a different type and then replacing it back again.? Don't ask me why but I believe that has solved some issues in the past.
Also, it could be your module is conflicting with another module such as a TCP server on the same port.
You also might try using Pre-200 from most of your program and then add a separate program that requires Post-200.? I've run different program versions in different slots I haven't had issues.? Shoot, I even have run SIMPL in one slot and Studio or D3PRO in another slot successfully.
