Is anybody using the Muse Research Receptor and GPO? I'm have a problem with installation.

After installing the "nks" files as instructed, and registering the product, GPO will not load a sound. It can't find the nks files, even though they reside exactly where it is looking (same place as the instructions). When looking to edit a file, GPO looks for a "wav" file for it's own instruments. There are no wav files on the CDs or installed on Receptor, but then again, it's looking for the "nks" files with wav data and can't find them.

I've reinstalled by the letter 3 times to no avail.
