Make sure you have your auto import running when you join a table. And after 1 or 2 hands when you are dealt in it'll pop up the hud. If not you can always click on HUD Options by the file, edit, view, menu and then click relaunch hud.
I just took a look at it, I would love to participate but, My own plans would interfere with the challenge. I'm depositing $600 in there in the next couple of weeks and am setting a goal to reach $40k, but thank you for the info!
Funnily the HUD just popped up in the carbon FR - don't know why it works now.
