Modules and Delphi

Question

I'm using dynamic link to load (BPL) modules into my app, the loading works fine with simple forms built into those moudles, but when adding more and more (third-) components and code to one form I get this error message "Invalid class typecast" for tha first time, 'cause for the second time the loading works ok, so I caught that exception and I load that module again, well that's my workaround, but Why does it happen?

Thanks in advance.

Sounds like the filename doesn't exist.
