QTObjects showing "No such interface supported" in Namemapping

Help, What used to work is no longer working & I have no idea why...



Trying to automate a 3rdParty  application that uses QTObjects using Test complete 9.1

the name mapping used to work but now its not recognising anything at run time..



using the object spy most properties are now showing as Error: No such interface supported"



I've checked the Install extentions & QTObjects & Open Applications are ticked..

 any ideas??
