Thanks for the fast reply! A little more information. I purchased DVD5 Platinum with the mobile option. The mobile option will not activate with the key sent to me and the trial is ended. The key I received was one to double click. I tried opening it in notepad to see if I could rip the key out of it and paste it in the registration key field, but the key opens up as a mess with no discernible key. I did a clean reinstall following the instruction in your sig and still have the same issue.
