not in sync: resp=0x33

Development Tools IDE 1.x

Hello All,
This is my first posting on the Arduino forum, so please bear with me.

Every time I try to upload any code from the GUI to my board (UNO) I get the error :avrdude: stk500_getsync(): not in sync: resp=0x33.
I am using Windows XP, and as I said above the UNO board. As far as I know I have my drivers installed correctly and such.
I was able to get my code uploaded a while back, and everything seemed to work fine, but then I didn't touch the board in a while and come back to it and I get this error.
I've searched all over the web and cannot find anyone with the same error, wondering if anyone has any ideas?

Thanks in advance
Tom

And your "interfacing with software on the computer" question was? This belongs in Installation and Troubleshooting.

Try unplugging everything from the headers of the Uno. Just leave the usb plugged in and try to upload the sketch again.
