The problem with licenses

Each time you log into the application , you must enter your license code. I have done free registration. What can I do ? My version is CZ 6.0.23421.0
Thank You.

Hi Jindrich,
are you using your license on more than one devices? We have a one license per device policy, so if you use it on more, you will be prompted for your license again.
Deactivate the license on one of your devices.
