Is it possible that you are using csound32.dll from the 5.01 zip package
(API version 1.00), but plugins from the Gogins 5.02 beta installer (API
version 1.01) ? If that is the case (quite likely, as OPCODEDIR is over-
written by the installer), you could just replace the DLL with the one
installed by 5.02 beta, renaming the file to csound32.dll if necessary.

The reason why the old csound32.dll library does not accept the new
plugins is that a new function was added to the plugin API (hence the
API version change from 1.00 to 1.01). However, there should be no
problem the other way, i.e. using old plugins or hosts built for 5.00
or 5.01 with the new 5.02 DLL file.
