If you have no problem using it before, you need to check if the license you purchased has expired. If you have never registered, it may be due to network reason that you did not actually complete the registration.
Firstly please make sure the license code was entered correctly without any misspelling or any space before or after the license info as our registration system is case sensitive. Then please check whether there is any special characters in your registration name. If you have received an user ID with special characters in it, please contact us to apply for a new one.
To register Joyoshare software, you should firstly install the program on your computer. After launching the program, click the menu icon at the top-right corner of the software. Then click the Register button in the drop-down list. There will be a popup dialog window requiring you enter license name and code. You should then enter the Name and Code, and click OK to register it as a full version.
If you use the program with a user account that has no administrative privileges, the program may go back to evaluation version once you logoff. You can solve this problem by installing the program as administrator. To do this, please right-click on the setup file (.exe) and select "Run as administrator". Then you should enter the administrator's password to install the program again.
