My EOS utility isn't working, what can be the source of the problem?

Question

My camera is a Canon EOS 40D. One of the programs it comes with is the EOS utility, which lets you shoot remotely. It worked fine the first time I used it, but I never really used it. Now that I need it, it isnt working. =/

Does anyone have any idea why it wont work? I can open it it, I just can't shoot remotely. I've reinstalled it, and looked at various sites.

Answer 1

Before you do anything else, call the Canon help line   800.OK-CANON and have them help you.

Answer 2

Speaking from first hand experience here with the very same camera:

1) make sure it isn't something as silly as forgetting to turn on the camera

2) don't try to use any USB extension cords, it only worked for me with the supplied cord alone.
