Your Logbook.BIN file is corrupted...
In your "Documents/Flight Simulator X Files" folder, you will find a file called
Logbook.BIN. (You can search for that filename, as well).
Delete that file. You will of course lose those previous flights, but so what. It will be rebuilt next time FSX starts.
This is a common issue: Apparently there is some buggy code within FSX. You can avoid it by NEVER deleting any entries from within FSX. Search simviation for "logbook editor". There is a freeware utility that will allow you to make changes, additions, or deletions outside of FSX. to reiterate:
After your flights, you should have no problem adding your text to the logbook entry from within FSX, but if you want to delete something, do it with the freeware tool.Computers suck, don't they!!!!
