Final Fantasy Hacktics

Thank you so much, I really appreciate it! 
Also, is there a reason why the Memory Card Generator keeps throwing me errors upon trying to create a new team or save?
Keeps telling me "Spreadsheet Error, Please Undo" and throwing me weird script errors I don't understand.

I guess I should have been more specific.
I'm confused about how battle hosting works. Where do I go to start an AI battle using teams I've configured? How do I add the teams into the game, and once I do that, how can I set up a tournament battle with the AI? Is that like a special option in-game? I know you can create teams using the team manager spreadsheet, but I have no idea how to get them into the game, and even then, I don't know how to start a battle between two teams ingame. I'm also confused on how the memory card creator works. Do I create a team INSIDE the creator, or am I supposed to load up a team I've created in the team designer? It's all very vague ;_;

I've seen AI tourneys, and I've seen how to manage and create a team for use in one, but how exactly do I go about hosting one of my own? What will I need to install besides FFT Arena, FFT, and the needed team building tools? I can't seem to find anything on this in the forums. Thanks!
