Visit us if you need our help. We'd be happy to work with you again.
Ask your accountant what kind of file she/he put in the thumb drive. If it is a *.QBW file, install the trial license of Pro 2020 to open it.
Once you can open it, you may have 2 options:
1. Purchase the license of QB Desktop. You may purchase directly to company or thru a partner to get the lower price., or
2. Migrate it to QB Online
