Help Getting Started With Arduino

I just reformatted my computer recently, and when I reinstalled the Arduino programming software and FTDI drivers, it, simply put, doesn't work. Everything installed okay, and my computer recognizes my Arduino (its an Arduino Decemelia with an ATMEGA168, and I set the software to this under the tools/board menu), but when I try to upload a program, it says the following:
"
avrdude: stk500_getsync(): not in sync: resp=0x00
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51
"
I know that this board has a bootloader because the pin 13 LED flashes when I turn it on, or when I press the reset button.

I also know that this board does, in fact, work, because it worked before I reformatted my computer. I did, however, have earlier versions of the drivers and programming software installed.

Please help me, thank you

Make sure it's using the correct comm port. Go into your device drivers (my computer or computer, right click>>properties >> device manager while the duino's plugged in, look for 'ports'. On mine it's com11.
I just checked the arduino forums by searching "expect=0x14, resp=0x51" and found your avrdude error - The administrators said they might have accidentally put the NG bootloader on a deicemelia.

Try hitting the reset button, THEN try to upload your sketch. It's a workaround - To fix it you need an FTDI hardware programmer to burn the correct bootloader into the chip.

another person attests to reinstalling the ftdi drivers...try that? *(as zerogx suggest)

try uninstalling all the software, and using the previos version you were using... also try, rebooting.
