Hi George,

It sounds like you're trying to use a 16 bit library with a 32 bit executable (or the other way around). You are running 5.0 or higher I assume. You can check the library by right clicking the filename and selecting the properties option. If there's a version tab, then it's a 32 bit library. 16 bit otherwise.

Other than this, I don't have an idea.
