click boxes revert to continue when file moved

For a long time I have been the only Captivate user in my department as a result, I just left the primary file on my hard drive and just put copies in our network drive as a backup. When I did this, I just opened it to make sure it didn't get corrupted and then closed it without actually playing it.

Then recently my co-worker started using Captivate as well and we started collaborating so I had both of us put copies of our files on the network (keeping our original files on the respective hard drives for safety purposes). I opened her file and tried working with it when I noticed something - all the click boxes she had set to jump to specific slides had reverted to "Continue."

We quickly checked my network copies and the same thing was happening.

Thinking maybe it was the network causing that somehow, my co-worker tried copying the file from her laptop to her desktop with the same results.

Any ideas what is causing it and how to fix it?  We are both using Captivate 6 from Tech Communications Suite 4. (We do plan to upgrade to suite 5 shortly.)

Thanks in advance
