Lost all XP

I was sitting in the East 3 Plaza lobby with my friends playing poker and after I stepped away from the table it said that I had 0 xp, Can I get any help? I had just recently unlocked the Golden Jetpack and gotten a bunch of trophys from minigolf.

It appears that I got some support with my XP issue, But I am still level 0 in the Plaza. I got my XP in Minigolf back but that was all.
