I think that IB should fess up to their mistakes and "eat" whatever losses they have caused.
I had a similar experience with cybercorp about a year ago, and they without any arguments or hesitation accepted their mistake and refunded me the loss caused by their system failure.
[in my case CyberTrader refused to exit a trade. I didn't get out until I got someone at Cyber on the phone and they manually closed out the position]
