Check with your purchasing credit card to see what kind of protection they offer. Many cards offer warranty protection above the standard warranty timeframe and will likely offer support for a company that goes under during your warranty period. This is what I'm doing currently.
You can also try to contact your state's AG as they typically handle these types of shady warranty situations but that is likely to be a lot more work.
