How to fix a problem of a program asking to enter code after I already purchased the program?
you just need to make sure that you registered the software, follow teh next steps:
Open the program, then click Menu or the green button at the top left-hand side of the screen
Click on Register Software
Enter your registration code without blank spaces after or before
Click Register and you should then see "Licensed software" at the top.
Once you have done this, you are ready. Restart the program in any case.
