Can't find SSD4 in VSTi manager

The folder which it is the “ssdsampler.dll” is added in the plugin manager (C:/program files/steinberg/vstplugins) and recognize it all my plugins and VSTi except this (Steven Slate Drums 4).

In Cubase 7 works fine. I don’t know what I have to do at this point,

Windows 8.1 64 bit.

everything is OK.

Even re-installing SSD4 in a different folder.
Before I had in Steinberg/VSTPlugins folder
Now is reinstalled in Steinberg/Cubase 8/VSTPlugins.

Then, I start Cubase (load screen) and says at the bottom of the screen:
“Initializing: VST 2.x Plugin -> SsdSampler”

And Cubase get stucked at this point and doesn’t continue. (I’ve been waiting for more than 30 minutes)

I’m in Win 8.1 64 bit

Strange, this just happened to me as well and I just completed a project with SSD4 last week, all of a sudden it could not be found:( CB7 it works fine.

I resolved by running the SsdSampler.dll through JBridge, I know it’s was 64bit to begin with, but this did the trick for me.
