Yes, I had that exact same error and I believe there was another thread on this recently.  There was no red error like Lisa is referring to.

In my case, it fixed itself after the next update came out.  Please make sure you have the most recent updates installed, including "Repair Updates".  I am thinking once you do that, your problem will go away.

Those boxes always show up as a red error in the Forms in Use list and a pink checkbox on the form screen......if NO red errors are showing for anything and you know you have missing info, then you may have a problem, but closing the client file and reopening would probably fix that.

Thanks Lisa, this corrected my issue.
