How do I use the Wub?

I purchased and mpc one and also mpc 2 DAW, have downloaded and loaded the wub plugin, and although it shows up if i try to export an expansion, it doesn't show in the expansion browser, and nor do is it show as a plugin on my mpc.

Total total newb, but please be good to me.

The wub is a plug-in expansion, not a sample expansion, it cannot be exported to standalone, it shouldn't even be there on the export screen. It's purely for use in the MPC software. Create a plug-in track, assign the wub and select a patch
