I have Sound Blaster Audigy 2ZS soundcard and every time I reformat my hard drive and update the software of the soundcard,the old version that was on the installation CD and the new version are both on my computer. For example, on the installation Cd I have Media Source 3.30.21 and the new updated version is 5.26.02. If I right-click on the speaker icon in the task bar and click Media source Player, it opens the 3.30.21 version. But if I go to a folder where I have music files and click a song, it opens with the Media Source Player 5.26.02. Why does it keep both? And how can I get rid of the old version? Also, both versions of MediaSource organizers are present on my computer.How can I uninstall the old version? Thank you very much for your time.(I do have the latest driver installed) I have a Dell XPS 600/Pentium D 3.00 ghz/2gb Ram/Bios version A11 and the chipset is Nvidianforce 4slix16.
