AAE ERROR 30001 - with Slate VBC FG GRAY

Hi , every time I try to open SLATE VBC- FG GRAY Compressor in Pro Tools 11.1.3 ( Windows 7 ) ....,



I get the ..., " Plugin could not be made active because a AAE error was encountered - AAE ERROR 30001 " message ? - this is in both Audio Suite , and as an insert on a track .



Strangely enough though ..., FG Mu , FG RED and the VBC Rack all will open up no worries , its just FG Gray that doesnt open and I get the error message :confused:



I have uninstalled and re-installed VBC , but no change ?



Any suggestions



Cheers
