Right, so you can setup multiple email endpoints and it will only tell you when ones fail to load. not when they succeed. So yours is named: 3-emailEndpointAddresses.sgd
This means that the following loaded successfully:
1-emailEndpointAddresses.sgd
2-emailEndpointAddresses.sgd
If you browse to the path you should see these there:
C:\Users\17R\AppData\Local\SequenceGenerator\Sequence Generator Pro\
I think you're chasing a red herring with this particular piece. Can you run a sequence and send me the log so I can see if there are any errors when a notification is sent?
Thanks,
