How can I make my computer recognize my TI 89 Titanium calculator?

I installed the TI 89 Titanium calculators installation disk before i plugged it in, like it told me to. At first things went well. I plugged in the cable after TI Connect was installed, and it installed the hardware. However, after it recognized the calc, i went on to update its OS. After I did, long and behold, the calc could no longer be recognized!!! it was OS version 3.00 for the TI 89, all i did was pressed the update link on the ti connect thing. Any help? The calculator is very new, probably 4 days old now and like i said before, the computer recognized it at first but now it cannot.

Do you have the connector cord from your calculator? Also, do you have the drivers for the calculator to connect to your computer?
