dll error when trying to playback recording

Goodday,

I am working on a trail version of Rapise. After successfully recording a script, I click on the Play button, but get the following message: ConnectionPointWrapper.dll is not properly registered! When I click Ok, the message is removed but the script is not played back. I am working on Windows 7, I have done a repair, deleted the dll and recreated it, but still displaying the same error if trying to playback. Can you please give advise as to what I am doing wrong.

Thank you
