A few days ago I had finally decided to up-grade my program.
It was working well for a couple of days until an Automatic Backup was performed resulting a "clean" window of the program after (no books were exhibited).
Closing and starting again and Restarting PC did not help.
When trying to open the program I get an error msg
stating: "List of index out of bound (-1)".
Re-installing the program (twice ) also did not help.
Please Help !
