Well that's a relief for me! I thought the same thing. The message changed to "you've used your code too many times" or something. I actually just emailed the club, so hopefully they'll sort it out.I'm getting it too. I thought perhaps because I had tried and rejected so many times that I might be locked out.
I was trying to get offered seats on the Medallion Club side.
I'm getting the same message for the North v Coll game that I'm trying to buy tickets for as well.
