Problem connecting Revive Drupal module with Revive backend

[rockmachine]

Hi there, hope you can help. i set up a Revive system on my server, to deliver ads for my news magazine, which is on the same server. the Revive backend itself looks great.

 

Now i installed the module for Drupal, installation also worked fine. Now on to the configuration, and there is the problem. i entered the data, but when i want to enter my Revive password and username, and hit the "sync zones" button, i get an "unexpected error" message. Below is what i entered (except username and password), maybe somebody could help 🙂 would be nice to get the Drupal module up and running, Revive looks very promising.
