Insite 8.7 and newer incal problem?

[68shifter]

Hello. I have Insite V8.7 and about a month ago my old incals stopped working. From my understanding something with the date/outdate. I installed the new ones but they only work with 8.8 I was hoping someone may have a work around, or old files I could purchase/reload etc.

Insite came pre-loaded on my laptop and the company I bought from has been less than helpful with this. Thanks
