MAKE A COPY OF YOUR *.VNU FILE BEFORE YOU INSTALL 5.9.2!!!!!!
It seems 5.9.2 messes up the internal file paths of EXISTING settings by duplicating the paths a few times. For instance, if you have an image c:\images\test.jpg, it is saved as c:\imagesc:\images\test.jpg! This seems to happen only to files that you added manually using the Settings | Add Files option. So, in my case, all my Photo Gallery and Flash Form files are "lost".
The fix is to Remove Files and re-add them all. Hopefully you remember where each file came from!
Hopefully this will save some people some headaches ... back to adding my 100+ files ...
[EDITED] WELL, DON'T UPGRADE ... it trashed my paths AGAIN!!!!! Going back to 5.9.1 ...

And, No, register.exe doesn't help as it will not run: "This application has failed to start ..."
