Are you having an outage right now? When I go to app.glip.com, I get a message saying "Scheduled Maintenance, We'll be back very soon. Thanks for your patience. Follow us on Twitter for updates."
I had a look at Twitter and there aren't any updates.
Also, I tried logging a ticket but got an "Internal Error" when trying to log in.
If there is an issue, the community would be a *great* place to put a post.
