need help/logic pro 9 and EZ drummer

Downloaded EZdrummer for logic pro 9. Can't find it, can't open it, doesn't come up as a plug in. Scanned my AU's and says it's there validated but still........... no EZdrummer.

Any clues anyone?

Have you checked your Downloads folder.

EZ drummer in logic 9 as a plug-in.

Thanks Gandalph.
Yes it's there in my download folder and have re installed a couple of times. Each time successfully installed it tells me.
Logic can't find it as a plugin. and I don't know how to get it to find it.
Driving me nuts.
