they have a support forum, and I would try posting the question in that forum. We would deal with media player in this forum. http://acdsystems.custhelp.com /cgi-bin/acdsystems.cfg/ php/enduser/ask.php
They also have a support tech that you can contact at above link. Take the spaces out of the above link before copy paste to browser window.
Another option is to un-install ACDsee, then reinstall it. It may have an error in the installation.
