Why am I Getting Pmmain, Program Error, or Main Program Message on simulation?

This article is from the previous version of ProcessModel and is kept for reference.

LegacyHow this worked in the previous version

When the model is simulated it crashes ProcessModel at 312 hours, displaying any of the following error message:

There are 24/7 shift files in use.

Having 24/7 shift files is the same as not having a shift file at all. Remove the shift file reference.
