How do i set up WebSMS fishtext connector?

My gf tried to download fishtext today on her htc phone which uses android. It said she needed this connector in order to use fishtext. (i have the iphone and downloaded fishtext in a matter of .5 seconds and had NO problem). We downloaded the connector, no problem but the option the send a message once in the app was un-pushable. I went to change provider and instead of saying fishtext there, as it should, i said something about having to check the preferences. I don't know what to do now to link the 2 apps together or to make the websms app realize we want to use fishtext. PLEASE HELP?!! What do I do?
