Ape Apps

As of today... the app, which I have used on my android phone for several years... is dead in the water. My user name and password are accurate, I had my network engineer husband change them, just in case. But it keeps giving me the same error: "Connection Failure -- Network browser was unable to connect using the settings provided. Please check your settings and try again." First I tried deleting (forgetting) the original server nickname, which it did. Then I tried uninstalling and reinstalling which it did but somehow it retrieved the original server name? From where I do not know... in any case, I REALLY like the simplicity of this network browser and I'm seriously bummed out... HELP?
