Sounds like your setting got changed from a full keyboard setup to a compact one. I am not sure where you change it on the 360 but I think there is a spot in the Final Fantasy menu which allows you to change it.
I think this is what you were looking for, if not sorry and disregard this post.
**The above poster was me, I forgot to change settings when I moved over to this computer**
Also you can try to set the Compact Keyboard I think in the playonline viewer if I remember correctly.
