The Grand3 64Bit+Cubase 7 LE 64 Bit not displayed


The Grand3 works pretty fine as standalone. I am able to use NI pianos as vst-plugin in Cubase 7 LE, but when trying to use the grand 3 as VST Plugin and clicking on “edit instrument” I always get an error: "A serious problem has occured: please try to save your project under another name and then restart Cubase LE AI Elements 7.exe. If this problem persists please contact Steinberg Technical Support with a description of what you do to create this problem, and the created file C:\Users\Sendel\Documents\Steinberg\CrashDumps\Cubase LE 64bit 2014.6.27 20.26.dmp. Click “OK” to be informed about further occurences of serious problems, or “Cancel” ti suppress these warnings in case of cascading warnings!

I am wondering why steinbergs software is not able to work together while NI has no problems doing it? What is wrong with my setup? Is this a known issue? Is this just with 64 bit edition?

My system config:
Windows 7 Professional (64bit)
16 GB Ram
Core i5-2300 CPU (2.8GHz)
Cubase LE 7.0.7 (2277) 64 Bit
The Grand 3 v4.0.2.78 v3.0.0 Standalone 64 Bit

The Update to The Grand 3.1 solved it ( v4.0.3.220 v3.1.0 Standalone2.1.2.830 64bit )
