Z3TA+2 Standalone crash

Hi All,
Long long time ago myself and some others were asking about below situation. I wanted to give my question another shot here in the Forum, maybe some of the code-crusher amongst you have found out something about this issue or are able to give some advice...I would really like to be able to use Z3TA+2 also in standalone mode
 
Running from within Sonar Z3TA+2 runs just fine, no Problems.
Also starting the synth in standalone mode works just fine UNTILL I try to set the audio/midi settings. Then Crash.
 
I understand from the crash-dump that there is a problem with Z3TA accessing the audio driver (VS700Set)
but I was wondering if anyone could give more insight in the exact meaning of the codes/id listed.
Previous Versions of Z3TA did not have this problem. I believe it started since VST3 was introduced so I am presuming that it is a "fault" in the code and nothing which I could influence through some special Settings/registry stuff etc.??
I am by the way running Win and the Programmes as admin.
