Additive drums

Has anybody ever tried using Additive drums with LE5?
Additive allow you to download a version to test out before buying the product. It is the full version but only has snare and kick just so you can see if it will work with your software.
I can see it in the VST list but when I make an instrument track and try to load it in I get error messages.
They do support Cubase but are a bit vague as to if that includes the LE versions.
Any help appreciated.

Hi,I have AI 6 AD drums work with it. Go to devices at top of page > click VST Instruments ,click in the space you should see AD Drum,click on it ,AD will open & an instrument track will be created.
