Prior to installing Picasa, I could import pics from camera using other picture applications, but now the others are not recognizing the SD card.  It doesn't even show as a device on the Computer.  I can only import them into Picaso and I want to import them in RAW format, which Picaso does not seem to allow.  I would like to import them into Corel Photo Paint but it can't see the card either.    Can anyone pls help?
