Craig Brown on EZKeys not in Plugins in ProTools 10

I have not been able to get PT10 to recognize EZKeys Studio Grand as a plug in. I have EZ Drummer and some expansion packs that work perfectly and expected EZKeys to install the same way, but can't seem to make it work. The stand alone works fine, so I am able to drag and drop piano parts, but don't have the functionality of the superior recording etc. of the studio grand. Running PT 10, on 64Bit system. installing the files for 64 bit (but I have tried 32 as well) also, am attempting it on stereo instrument track, setting up the same as EZDrummer and I have tried reinstalling a couple of different times.
Any ideas?
