windows 7 problems uploading to board

hi

i'm have problems to upload sketchs to my arduino duemillanove board.

-i've just instaled windows 7 x32 -i've the right serial port selected -and i have the right board selected too (arduino duemillanove w/ atmega328 - i have java instaled edit: i also tryed compatibility mode too...nothing

i think the atmega32 it's not damaged because it's still blinking the the blink sketchs.

i'm getting this erro: avrdude: stk500_getsync(): not in sync: resp=0x30 avrdude: stk500_disable(): protocol error, expect=0x14, resp=0xe0

any ideas?

thanks

forgot to instal the ftdi drivers...sorry
