'Cannot run two instances of VST Connect' error

I’d like to not yet give up on this. What does “didn’t work” mean exactly? Your last problem was that you couldn’t log in and we recommended to update to the latest version. If you create an empty project and apply “Create VST Connect”, what doesn’t work?
You may also want to look at https://www.connectvst.com but we are also here to help if you still have problems. Thanks for your patience.
