Thanks for the reply. If I’m reading you correctly it’s best to totally uninstall Groove Agent and then install it rather than select reinstall from the list, which I’ve done twice now. Ok I’ll try that next. I’m finding it odd though that the 32 bit standalone works perfectly with all kits available. But yeah, if Groove Agent 5 is to have a superior library system and hopefully solve the problem that would be cool. Is it on the horizon do you know?
