DVD copying problems.?

I just purchased a download of 1CLICK DVD COPY. I had to also download DVD43 to make back-up copies of some of my movies. I used it successfully on two encrypted movies and was very pleased with the quality. The next day I attempted to copy other encrypted movies but it didn't work. I keep getting a pop-up message that says "Cant connect. DVD43 driver must be installed, up to date and active". Do I need to download DVD43 again? How can I make sure i'm getting the latest version of DVD43? Is there another/better decrypter I should consider? Please provide a link to your suggested site. I sent an e-mail to 1CLICK service center yesterday and have not received any response (so much for customer service). Thanks for your help.
