Sorry to be the bearer of bad news but row aa is not front row. There is a pit area in front with 5 rows in it. I too got row aa for one night and row bb for the other night. Maybe this is actually better for you as it puts you at a better angle to the stage. See you there.
Here's the eBay link to show the correct seating chart. You will have to copy and paste it:
