I got my arduino like 6 months ago and it worked perfectly fine. I kinda learned how to use it but I decided to take a break for a while. Now when I try to use it, it doesn't want to work. I used it on a Windows XP when it worked and now I'm trying to use it on my laptop which is a Windows 7. It is a Duemilanove with an ATMega328. When I try to upload any code, it says,
"avrdude: stk500_getsync(): not in sync: resp=0x30 avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51"
I've read other forum topics on this but nothing helps.
