Just noticed this happen yesterday - sitting at a table and both Hold Em manager and the HUD would not import data for a player. Not sure if it was because of the name of the player (it included a "?" at the end of his/her name) or what, but i tried stopping and starting the HUD multiple times / auto import etc and it refused to import data on this specific player and the HUD remained w/ a hand count of 1 w/ all 0's for stats.
