Reason

This problem may be caused from corruption or errrors in the database. Follow the steps below to solve the problem.

Steps to Resolve

Option 1

The database should be compacted. To do this follow these steps.

1.) Open Flowmaster without opening the model file.

2.) Go to Tools > Database Utilities > Compact Database.

3.) When the Open menu appears, select the .MDB file.

4.) The Database file will be compacted and updated.

4.) Once this process is complete please reopen the Flowmaster file.

6.) The model should open as normal.
