I think with Alphabetty, from what I've seen in the past, that even though the levels are shown on the map, they are not available at the end. The last level now is 380 so we're both on the same one. Just need to wait for more levels now.
I had the same problem on level 380. I made sure I was connected to facebook on the game, then Uninstalled AlphaBetty and reinstalled it. it worked and now I'm able to play level 381.
