For those who have issues with registration. Problem is in the application itself. In the registration dialog application will not tell you what is wrong with inserted data. In my case it was too short password (must be at least 6-digits long). I did ma registration process on their website: http://www.apowersoft.com Only the site told me that my password was short. I changed it and finally my registration was succesfull. Then I inserted registered mail and password into login dialog inside application and it loged in. After that I was able to input activation code. Application states only it is personal license, nothing more. The verification code Apower is sending is really only 4 digit and is OK (I have no problems with this).
Creator of this software have to repair thos log in and sign up dialogs as well as at least czech translation which is now horrible (maybe other translations too).
