Would it be possible to add something to material files to be able to easily tell which version it was data fit for? If you try to use a material with CRIMS that was fitted for a version previous to the one you're trying to run it in, you get a warning that says:

The "Actual version: #17190, Required version: #17420" doesn't seem to correspond to a specific version number, so it's hard to tell which version it would need to be run in. Looking at the CRIMS model coefficients, you can tell when the data was last modified, but it still doesn't 100% confirm which version it was for.
