I can't cancel this dispute with Steam?

[Flame558]

I accidentally made a dispute with Steam on the purchase of Team Fortress 2. They say as soon as I cancel the dispute my Steam account will automatically unlock. Alright, that's all well and good, but It won't let me cancel the dispute. IT keeps saying 'Error in canceling dispute' When I click it. Any help?

Don't cancel the dispute, once it's closed it can't be reopened.  Ther is no "auto" unlock when a dispute is closed.
