Upgrade to NT 5 (Windows 2000) whenever you can.. this is the most stable Windows version I know of to work with PD.

I've got thesame problem. Usually when this occurs the filename extension is incorrect for the platform, the filename doesn't match that of the setup routine, or the subroutine wasn't declared extern. I tried all that, but I didn't get far. In a previous post Miller noted that this could very well be an incompatability problem with MSVC++. i'm currently using version 6, and there are several types of DLL files I could generate. I really don't have a clue what the correct settings are for PD. The external tutorial is now at least 5 years old, I highly recommend upgrading it to present time standards, it doesn't say anything about a major compiler that a lot of people are using.. More help of course is very much appreciated!
