Err 99 can also be a battery or card error and can be easily fixed, so if you haven't yet, try these things:
1 - turn camera off, pop card out, close card door, open card door, put card back in, turn on camera, test at least 10 shots.
2 - do the exact same thing but with the battery. I had a battery freak out on my during a shoot once and I had to pop it out after every few shots. Once I got to shoot 8+ in a row, it didn't freak out any more. Same battery has never caused a problem before or since, so it's obviously gremlins.
have you tried this? except the gremlins part. happened to me once. i took everything apart. used a blower on the contacts. worked after i assembled everything back again.
also there is a canon service center near ortigas business district... liberty center, mandaluyong city. depends on the problem it can take just a couple of hours...or 3 months if you're unlucky
