Piuk reads this thread so this is probably the best way to get in contact with him. Are the transactions confirmed on the expired address - or are they not confirming? If the latter, I would just wait for them to confirm, I've recently had some tx that take a day to confirm, even with a fee... the network is just very overloaded at the moment.

The transaction that was sent to one of my "Shared Send" expired addresses now has over 100 confirmations. It's for $20k.
The other unconfirmed transactions I would wait for, but they are transactions sent out to clients who bought the btc from us, and who are now also joining in on being pissed.
