Problem loading Massive Threat into Massive.

I've just purchased Massive Threat, I can play it fine through Kore Player but I'd like to be able to edit the sounds in a bit more detail. Anybody know how I can load Massive Threat into Massive?

I've tried using the browser in Massive to find the library of sounds but there doesn't seem to be anything in the Massive Threat folder that I can load. I've also tried re-installing Massive Threat but it hasn't helped. All that's in my 'Massive Threat Library' is a folder called 'Documentation' which leads to another folder called 'License Agreements' (containing three text files) and the Massive Threat manual (which didn't offer anything useful on the subject).

If anyone can help it'd be massively appreciated.

No pun intended.

No need for anyone to offer suggestions, I figured it out.
