Hi, George
George, the gateway you refer is the old version one, Java-based, we just released a completely rewritten version, 2.0, not Java-based, much improved compared to this one. My advice is to uninstall the one you have and to install this new one, even in Beta. Please check this:

Any feedback will be welcomed.
