Things have just went terribly wrong!

My email i just sent pokerroom explains...

Hi,I booked my flight today for Las Vegas and was advised that as i have a minor driving conviction from 4 years ago (driving while my insurance had expired) i may need a visa.I telephoned the american embassay and they confirmed i would need a visa and this could take up to 8 weeks, i explained the situation and they said as it is a professional event i could contact someone else and they may be able to do something which i have done but im due to be in vegas in 11 days so am holding no hope out for this.Could you advise me on anything you can do either to help sort this or if buy in for this event could be used for some other event at a later date when i would have had time to sort visas etc or any other solutions you could offer.RegardsMarky_Crash
