The file name is change to short mode without my consent

The file name auto change to short mode without my consent. Please Help me.

The only known cause of that is using a pirate version (or having used one in the past and not undone all the things it did).

Thanks for help, but I was downloaded from the official site. It is the version 9.5.6.0.3937.

Contact GPSoftware for assistance. They may be able to suggest something to try.
