I get this error: Failed to locate assemble ´Bass.NET, version=2.3.1.2, culture=neutral, publickeytoken=b....: everytime i try to open Mediaportal, i have tried to upgrade my DirectX, repared .Net framework 2.0.
This can happen if you do a mediaportal repair on an SVN'd install through add/remove programs or if you run MP under a different user account, re-apply the SVN you're running (or later) can resolve it.
