I have seen similar things. This is usually caused by you testing the COM within the VFP IDE and then leaving it open.

The usual things to do is:

1. Shutdown VFP
2. Restart IIS since the COM will be cached in IIS.
3. Recompile the VFP DLL
4. In VS delete the Reference to the VFP Interop.Dll in the BIN directory and re create it.
5. Rebuild the solution. All should be well now.
