I've had this situation too--for some reason the agents in the clubs can't do anything for you within 60 minutes of flight departure, and you have to go to the gate to try to get helped.
The agents in the club have, over the years, been outstanding and have come up with things like free hotel rooms and meal vouchers, as well as confirmed upgrades to F on next morning flights. Over the long haul, the club agents will help you, and their help will be invaluable.
