HI,

‘Error: Couldn’t resolve Demo Web API interfaces’

Suddenly got this message alert coming up every few moments in Pro Tools Artist - been using BDF3 fine for months within a studio setup with Roland drum kit. Tried latest licence manager - still not sorted. As soon as I remove the BFD3 plugin from the instrument track, message stops.

What do you mean?  
Is there an issue with the licence manager?

I read a comment elsewhere that this issue was resolved by running the latest licence manager - but that didn’t work for me.

Only had the alert issue today - no idea why its happening.

I’ve just sorted the problem by updating to version 3.4.5.28
