I just tried 8/18 and 8/25 evenings and the code worked. What dates are you trying?
Ticketmaster, yes. Try a different browser, or restart the browser you are using. It must just be stuck somehow. The code, all caps, definitely worked for me.
2nd row was just released for next week's performances. Not for the discount code - they're premium $229 tickets. But it seems crazy to me to wait until one week out to release an entire row.
