I'm not sure if you would be able to deduct that loss. Can you calculate how much business you lost because of it? That is a good question for a tax pro.
On the link above, if you go to page 93 it discusses what can be considered a lose. That section towards the end will also show you how to file a Schedule D on your 1040 should you be able to claim it as a loss.
