Magento "Payment Transaction Failed" fix

We have 2 stores in Magento. US works ok but AU throws this error when customer is at checkout:

SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry '378503815' for key 'UNQ_SALES_FLAT_ORDER_INCREMENT_ID'

Also check screen.

It might have to do with Fooman custom order number extension that we had on old magento but now that we updated to it's no longer supported. But new orders are placed successfully on US store.

There are more bugs in the system that need fixing so if you do this job well and for a competitive price will have more work. A lot more.
