Cubase 6.5.4 zplanelibs.dll errors, padshop errors etc

Hello to one and all,

I am having a lot of crashes relating to this zplane dll in cubase 6.5.4.i am aware that this is related to the timestretching function.

How can i eradicate these? I have never used a DAW as unreliable.

The system will crash at any given moment and now more recently padshop which will not play back anything other than the default pure sine wave. It will not play presets or any of the samples in the wave folder and sometimes having selected it as a vst instrument channel the button to bring up the padshop interface is not highlighted and has no affect then leading to a runtime error.

I have raised an issue at the support desk, currently waiting for a reply. Anyone else had any similar problems?
