I have recently started to experience the same problem. I
have been running in RH7 for about 3 months now with the same
projects that I converted from RH6 with no issues, all of my
projects were created, stored and operated locally (good), however
lately I have not been able to open my projects on the first try. I
have attempted to delete the .CPD file and still no go. I did
notice that when I am loading my project in RH7, RH is creating an
MS Access Lock Database file, .LDB, which reading into previous
postings about this file type might be the problem, however even
upon deleting both the .LDB/.CPD files and re-opening the project
it still crashes with the "RoboHelp must close" message. I do
eventually get the project to open after repeating this process
about 4-5x's however it is a royal pain and extremely frustrating.
The only change to my operating system was that my company
did recently upgrading my MS Office application from Office 2000 to
Office 2003 about 2 weeks ago (as my company is always years before
the times when it comes to upgrades, I had to fight tooth and nail
just to get to RH7

). I could not find any previous postings showing any
compatability isues, but could this be possibly causing the
problem?
