Problem Accessing Database

Hello,

I have WebMatrix 2.0 on account of me still being on XP, and I haven't used it for a while and although I can 'run' my sites ok, when I click on the Database link and try to access the databases I get the following error and wonder what I'm doing wrong (I've uninstalled and reinstalled everything but same thing):

Exception of type 'Microsoft.WebMatrix.DatabaseManager.DependenciesMissingException' was thrown.

Microsoft.WebMatrix.DatabaseManager.DependenciesMissingException: Exception of type 'Microsoft.WebMatrix.DatabaseManager.DependenciesMissingException' was thrown.
