I purchased software Mac iPod Video Converter from this company www.mp4converter.net When I register to get the full version, a strange thing happened. The software doesn’t allow me to copy and past the license code. I tried several times with no success. I download the software again and install it. This time I can copy and past the code. This is really strange. Is there some problem with the software or with my operation? So queer. Any one can solve this for me?
