I have no notification from the game or otherwise that the exp has been installed. I've gone to the town which has the guild option and the only thing I can do is recruit soldiers. I have uninstalled the whole thing and reinstalled. What am I doing wrong?

Play until Kyrie gets her special class (which happens early in the game), then play one more story battle, and by then the first missions should become available.

I am waaaaay past that
