try to start and can t upload sketches

Hi there, i m just trying to get started with arduino diecimila but i can t upload the example sketch blink.
i did everything they tell to check in the troubleshooting, the board s not laying on metal, tried to reset and the orange LED blinked once, etc..
i m running windows xp home edition.
the message shown is the following:
avrdude: stk500_getsync(): not in sync: resp=0x00
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51
anybody can help?

well i figured it out, as supposed it was something stupid: the drivers weren t installed properly, didn t get why windows asked me two times for them..
