LOL sounds right!

It is the LoadLibrary that is failing; it should be obvious that if it 
was a simple GetProcAddress that was failing, Python would simply throw 
an exception rather than displaying the ugly dialog box you see.

The problem is that some *other* DLL in the chain of dependencies is 
failing to load; please re-adjust your perceptions of your own knowledge 
and re-read John's initial response - if you follow his instructions 
that should all become quite obvious.
