Server Not Connecting

I have been using VPN express for the past 5-6 months - Flawless - Great clarity for VoIP calls - But its not connecting for the last one week ???? Can someone help - As there is no support email or anything for this app. It simply says that the server is not accessible at this point in time. Please fix asap. Thanks
