Cache went corrupt now windchill will not connect with inventor?

Hi All,

Our company has been using Windchill with Autodesk Inventor. We seem to be having a lot of cache's go corrupt. When I was synchronizing my workspace today, Windchill crashed and wouldn't open back up. If you watched the windchill work group manager in the task manager, it opened and closed in <10 seconds. This is a sign of a corrupt workspace so I went ahead and renamed my cache to allow windchill to rebuild a new cache. Now when i go to open Windchill, it wont connect to inventor. It is giving me an error that says "CAD adapter DLL load failed:". Does anyone know what might be causing this and what I can do to avoid corrupt caches in the future?
