Cannot open a prototype created by another user on the same version of JIM.
Both of us are now on the free version...
When attempting to open a prototype created by someone else (different PC), I get an error saying it was created on a newer version of JIM, but we are both using v9.1.10 - and, I can open all of my own files, including those created in older versions. The ONLY file I cannot open is the one that he created and asked me to review for him.
I have also tried opening all of the aforementioned files on an older version and, again, all but his open up just fine. Any guesses as to the cause??
Help?... (screenshots attached)
