Version 8.0.0 Crashes before finishing indexing

Nothing seems to help.  I even did clean re-install (cleared index, uninstalled, and re-installed).

Copernic at first seems to work just fine until it stops on a file (different files each time).  Sometimes it's a big file sometimes a small one (the last time it was a very simple PDF file only 232 KB).  It sometimes stops after10 minutes of indexing and sometimes after 1 hour.  Completely random.

Nothing helps at that time.  Pause,  exit, restart, etc..  Also, after it stopped, if I exit the tray application, I can't restart Copernic.  Despite exiting, there are still two processes running.  At that point I have to end the processes and only after that I can re-start Copernic.

Never had that problem with any previous version. 

Tech support keeps suggesting that I do things that I already did (and wrote to them that I did them).  They don't seem to be reading my explanations.
