OutLook 2000 and Mediaworks 98

I have a Diamond Monster MX300 sound card. I downloaded an update from the Diamond Multimedia website for my sound card. After the installation I found that Mediaworks98 was part of the update. Mediaworks98 is a application that plays audio cd’s andwav files. While Mediaworks is playing, I open Outlook 2000 to check my email and the application partially opens then freezes. When I not running Mediaworks 98 Outlook 2000 opens normally. I went to Mediaworks 98 website for support but none was available. What is the problem? Can you help?
