To Whom Can Help,

I have been using the Substance material forum made and beta plug-in to add Substance materials into my 3ds max 2018 files for the last year or so. Yesterday, they came out with an official release which I quickly installed. The problem I'm now facing is... it didn't do anything to uninstall the old plug-in files. I got rid on the one erroring 3ds max as duplicate materials, but now I'm opening files with previous Substance materials and it comes up with critical/crash level errors. What files do I need to uninstall to make this work better from the previous installs to make it work again? I'm already assuming I probably need to relink the Substance material file.

Thanks ahead.
