Today I have bought the program.
I have received a registration code.
However there is a problem.
After new restart of the program, it loses a code.
I am compelled to enter a code each time.
I ask to help me.

I have Windows-7
Hallo from Russia.

The problem here must be that for some reason Tabbles is not able to write the serial number in the registry. Could you please if your antivirus is monitoring the registry too? Or if your user has the rights to write in the registry?
Thanks,
Andrea
