Can you explain to me what that zip file you attached is?

Have you already tried to delete everything and reinstall BP? (It seems that the database containing the installation parameters has been corrupted.)

Giorgio Yes, repeatedly!


Unfortunately, I do not have a Q68 to help you. I will try to ask Italian users if they have had the same problem ...

Specifically:
- How many records can it maintain?
- How many fields can a _ddf file have?
