Sorry to hear that mm :(
I did try and make it as clear as possible in the opening Forum Thread post:
Corwyn: *** Remember, to be in the running for any prizes, you must take and post either a VIDEO record or SCREEN SHOTS with PROOF OF CLUBS used, along with both f9 & b9 CARDS and all the STATS!!!!! (see post below for details) ***
... and the information is also in the officlal tourney page/leaderboard description, but obviously, with it being in the main game client, there will be players who don't look at either before playing.
Nevertheless, I feel bad that this aspect of the TIO events has taken players by surprise, and that the screenshot requirements seem too difficult for many players. This has turned into much more of a headache than I thought possible, for all concerned. I'm sorry!
P.S. I was very pleased to come back from my trip and see you'd won the July Glenmorangie VT event at Legend level. Congrats on such a big win!
