Warning! This story does not have a happy ending.
So, after emailing BFGs tech support/RMA service for the past week and a bit, I have had absolutely no response. It appears their RMA partner in Wales no longer works with them (you ship the cards to them, they test them, and ship them onto BFG US for a refund), and they have all but pulled out of Europe. Despite the chairman claiming in interviews that they would continue to support the owners of cards that were under warranty, this has certainly not been my experience of the situation. As far as I can tell my RMA case is dead in the water, and since its a US company and I live in the UK, I have very little comeback.
Cant afford a new card either...
I am sad
