Until a week or so ago, my Canon PowerShot SD1000 camera worked just fine. I bought a new Gateway DX4860 desktop last December and was importing pictures from my camera using Picasa 3 with no problem -- did it several times. (I connect with a USB cord.) Then about a week ago I could not get my computer to "see" the SD1000 -- absolutely nothing. A friend thinks that the driver is corrupted, but I can't seem to delete any driver for my SD1000 camera. My wife has a SD600 and that connects to my new desktop OK. I even tried putting the memory chip from my SD1000 into her SD600 and that works OK, but her chip in my camera does nothing and the SD1000 camera is still not recognized. Another friend suggested connecting my SD1000 and then looking at DeviceMgr -> PortableDevices, but my Canon camera doesn't show up there. When it's connected, it isn't recognized in the Start -> Device and Printers window (but the SD600, when connected, does show up there). If you have any clues about what's happening and how I can return to having my SD1000 recognized, I'll be most appreciative.
