Just bought a waterproof Olympus Tough 3000. Have connected to the pc, but the software doesn't start up automatically, so I click setup manually, it takes ages to install, then when its finished the software won't actually run - click the icon and nothing, just an error message about not being able to read the memory or something

Tried uninstalling/re-installing - same result. Thankfully I can actually "see" the photo folder on the camera by going through My Computer etc, and drag and drop photos onto the pc, but weirdly if I try an go in via My Picture/Retrieve pictures from scanner/camera, it can't "see" the camera (only the webcam we have connected). I'm not actually that bothered about using the Olympus software for file transfer and management (in fact I'd rather not, I'm just annoyed it won't work!), but I did want to use the editing software and I can't see to install that on its own, I have to go through the whole automatic setup proces, which arrives at the dead end described above.
Anyone had the same problems with this software?
If I can't get it working, anyone got any suggestions for just downloading the Olympus photo editing software, or suggestions for other free editing software?
Ta very much.
