Media Bay Problem In Updated Cubase 5.

Hello there, I updated to the last version in cubase 5 and when I open up media bay I can preview loops,samples and waves ,but when I start to navigate around in media bay and press for example location or any other part of the menu every thing freezes up ,also before freezing up the scan number stays on about 14,290 but the progress icon keeps spinning without The number changing.Every thing else works fine except the media bay freeze or hang.Before the update the media bay functions worked fine.If anyone could help it would be greatly appreciated thanks from Karmig.
