Not working – MoSIP Review

I depend on this app to call my family and friends, it was working perfectly until last update.now its not working at all since almost a month. Y the heck the developer ruined the already perfect working app . I am willing to pay the fees too. Its not working on my iphone 5 as well as on my ipad 4 . Please fix or less i"ll be deleting this app soon .
