Be sure that you are using GeoBase v2.0.3.1 files in your application.  There was a domain recycling problem with 2.0.3 that is corrected in this release. It mostly shows up under IS since it often creates multiple app domains. You need to ensure that you use both new dlls.

GeoBase v2.0.3.1 is available in the downloads section.
