Can't log in on the launcher it keeps telling me to set up a free trial account

I am currently subbed to FFXIV but I'm not on my main PC so at first I just copied my installation of FFXIV to my external, as I have done before, so I could play while I am not at home. When I run the launcher it went to a "Welcome to Final Fantasy XIV!" screen that says "The following steps are required in order to begin your free trial of FINAL FANTASY XIV: A Realm Reborn: Please follow the onscreen instructions to complete the required procedures." and just has a 'Next' button. There are no other options. So then I tried downloading the installer from http://www.finalfantasyxiv.com/playersdownload/na/ and reinstalling the launcher, it is giving me the same screen, not the normal login screen. Any ideas on how to fix this?

you need to uninstall the trial version of game before running the installer for the full version.
