TI-84 Plus C Silver Edition Connectivity Issues

[Samuel Frazee]

I recently purchased a TI-84 Plus C Silver Edition calculator.

The calculator seemed to be missing many of the programs that all of the other calculators I have seen have. I downloaded the programs and tried connecting the calculator to my computer using the included USB cable after installing TI-Connect CE.

A popup says, "Unknown Device Drivers installed." The calculator also does not show up in TI-Connect CE. I then tried the same with TI-Connect. I have tried it in all of the USB ports on my computer and also tried installing drivers through the device manager.. The current OS version is 4.0. Please help!
