I know you will hate this, but maybe it will save you next time. I belong to USAA insurance, and they insured most of my kit at 6500.00 US. Cost me 80.00 a year. The insurance--anything, dropped, stolen, fire, water, car accident, etc. Anything happens to my stuff, and they replace it no questions.
Just call Canon and tell them what happpned. THey'll give you instructions on shipping it to them, and if they can fix it. Really sorry that happened to you. But don't feel stupid. I've heard that happening to many people. My freind who is a professional photographer dropped his 100-400 L into salt water once.
