Hey BDL!
I bought the game on Steam and I had the same problem, which as far as I researched, seems to be related to computer users who have Intel Core processors. The opengl file you are talking about did help me for running the game on SP, but not for MP. After trying a lot of solutions from Steam forums and elsewhere, the only thing that worked in my case was to follow these steps:
Start -> Settings (Control Panel) -> System-> About -> Advanced System Settings (in the list on the right) -> [Advanced Options Tab] Settings in Perfomance section -> Data Execution Prevention Tab -> Turn on DEP for all programs and services except those I select -> Add "jk2mp.exe" -> Apply -> OK
I have Windows 10 like you, so the instructions should work with you as well, but if not (or if I mistranslated something), then just search how to access to Data Execution Prevention in a way it's display on your own PC.
Hope that works for you too or anybody else with this issue.
Peace out
