You can use the Kies software. It does not always work that reliably but you can use it with your Verizon phone. Try downloading the drivers for the phone again or restarting the computer and reconnect the phone. Often I have had to try connecting tow or three times before I get it to work, and in just bought a new computer in the last six weeks. Even in my brand new one it is about as reliable as on my size year old one... Pretty bummer as they have proprietary software we need to use but it works so intermittently.
Hope that helps some. Good luck.
Ps the drivers should download through Kies or you can get them directly from the Samsung website.
