trouble installing ionize cms

[eluser]intoitdaily[/eluser]
So I've been looking for a CMS in codeigniter and I came across a couple that were pretty difficult. Ionize, however, has been least difficult, but still doesn't work for me. I've built several sites in codeigniter, but nothing with it's own helpers or libraries and nothing with multiple languages, all of which Ionize CMS contain. Also, I've never deployed codeigniter where my applications/ directory is outside of my system/ directory. I thought that was weird.

Anyway, I installed it, just fine after a few attempts (the installation instructions are not thorough at all and have barely any troubleshooting. Anyway, the front-end of the CMS works, but the backend displays an error. I type in http://mydomain.com/admin, it forwards me to http://www.mydomain.com/en/admin/user/login, and displays this error:

An Error Was Encountered

Page Controller Error :

* No existing page or
* Unable to determine wich page should be displayed or
* Page translation not done in the default language : en

I have no idea how to handle this error. does anybody know what's going on here? Is there any more information you need to help diagnose the problem?
