Do you really need a driver? The best way to download pictures from your camera to your computer involves removing the memory card from the camera and plugging it into a card reader (either built-in to the computer or connected via USB). This is likely to be faster than connecting the camera to the computer, and won't run down your camera's batteries. Once the card is plugged in, it will appear to your computer as a removable drive. You can use the operating system's drag&drop facility to copy pictures from the card to the computer's hard drive, the same way you copy any other files. Or you can use any photo management program such as Picasa ( http://picasa.google.com ).

The soap is probably between the back light and the LCD itself, on one of the plastic Fresnel screens. You may be able to clean it off with Windex on a Q-tip. Remove back cover (can't give directions without knowing which model)

I've uploaded an expanded schematic of the 350D to this site which should hopefully appear in the next day or two - it gives you an idea of how to disassemble without being explicit instructions.
Hopefully this will help.

This sounds like the screw that always comes out in these has shorted out the flash circuit to the main body ground and shorted out two or three circuit boards.

Something is bad with the lens or it needs to have an upgraded circuit put it to make it compatible (if it is older). Usual cause of lens failure is the aperture unit. Almost impossible to get Sigma parts these days.

This is usually caused by impact or sticky liquid spillage that acts like glue holding the flash down

Set to 'one shot' auto focus and try again

Remove black side cover (two screws) and rear cover and check the rear circuit board for a missing screw in the lower right corner. Find screw and replace. If it did not short out the circuit you should see the function return. Other, send to Canon for circuit replacement

The rear circuit board lower right screw comes out on these and shorts out various parts of the circuits. Sometimes you can just put it back, sometimes it requires circuit replacement.

Error 5 is a flash error, and indicates the flash did not pop up . Usually caused by impact to the flash (flash stuck) or sticky liquid spillage that acts like glue to hold the flash down (clean spillage with Windex on a Q-tip).

CF pin assembly is soldered onto the main circuit board. Replacing this requires a soldering work station with a good heat gun

Yes. It should work using some software on your computer. More info can be found here: http://www.wikihow.com/Recover-Pictures-from-SD-Card

Err 99 usually means your lens contacts are dirty either on the lens itself or on the camera.

To isolate the cause of the issue, do the following: -
1. Turn off the camera.
2. Remove the lens, battery, and CF card.
3. Allow the camera to sit without power for approximately 20 minutes.
4. Insert only a fully charged battery, and turn on the camera.
5. Depress the shutter button as you would to take a picture.

Does the “ERR 99" message appear? If so, the camera may be faulty and requires a service. If it does not, then: -
1. Turn off the camera.
2. Insert the CF card.
3. Turn on the camera.
4. Format the CF card in the camera.
5. Depress the shutter button as you would to take a picture.

Does the “ERR 99" message appear? If so, then the CF card is faulty. Try a different card. If the message does not appear: -
1. Turn off the camera.
2. Clean the gold contacts on the lens by GENTLY rubbing them with a pencil eraser or soft cloth. Keeping the camera face pointing down, also clean the gold contacts on the camera, being careful that you do not let any debris fall into the camera body.
3. Reattach your lens.
4. Turn on the camera.
5. Depress the shutter button as you would to take a picture.

If the “ERR 99" message only appears when one particular lens is attached, then that lens should be examined by a service technician.
If you see the “ERR 99" with a different Canon lens attached, then the camera is faulty and should be serviced.

The 300D is known in some parts of the world as the Digital Rebel. You may download the Digital Rebel manual and more from http://www.usa.canon.com/cusa/support/consumer/eos_slr_camera_systems/eos_digital_slr_cameras/eos_digital_rebel#BrochuresAndManuals

Multiply the mm by 1.5 to get the actual range on a digital camera for any particular lens. Example...80-200 is actually 120-300mm. Then, to give you an idea of how that will look, every 50mm is like a 1x power on a pair of binoculars. Example...120=2.4 power, 300=6 power.
