I've no experience with that camera in particular, but I think I'd delete the device from the device manager and then reboot & follow the install process again. If it's a USB mass storage device, it might not have been 'unplugged' in the OS before it was disconnected. Depending on the device, this might be a problem. Most of the time it isn't, so I'm guessing here.

I agree with other's sentiments - non removable storage on digicams = bad.
