Question about Questions Regarding Purchase What do I do if the program doesn’t accept my license code?

Answer

When entering the license code, please pay attention to the following:

  1. Exact spelling is important – that includes case sensitivity!
  2. Carefully recheck the information you entered upon purchase. Maybe a typo occurred. It is important that the information you provided when purchasing the program (name and e-mail address) match the information you enter in the program.
  3. If you checked the information you provided and still are unable to activate the software, please contact out service team indicating your name and the e-mail address you provided when purchasing the program.
