The system cannot find the file specified. (Exception from HRESULT: 0×80070002)

Have you ever seen the error below? The error tells you that it cannot find a file but it does not mention the name of the file! In my case, I had a map with a script functoid that referenced an external assembly. It turns out that I copied this map from another project and the assembly reference was no longer valid. I should have encountered build errors but instead I had to deal with this issue at runtime.
