TCS 5 RoboHelp and FrameMaker links work and then stop

Hi,

I installed TCS 5 after installing a trial of RoboHelp 11.  After I installed, I opened a project from TCS 4 and I was able to update an existing linked FM book and Link to new files.    The FM files were converted ot FM 12 and the RoboHelp project was converted to RoboHelp 11.

Now, when I reopen the RoboHelp project, I cannot update or link to FrameMaker documents.

I am running Windows 7. I run both RH and FM as administrator and I have owner permissions to the Adobe folder.

I tried uninstalling and reinstalling TCS 5 and the behavior is consistent.  Is there some registry entry or something i should look for?
