Programmer is not responding on USB Arduino

Using windows XP, have installed the 2 ftdi drivers. Am using 0005 of software, but my arduino is old (2005), so no version number. I have the right port and speed selected.

So not responding. Any ideas?

How can I upgrade the bootloader? (thinking that the old version is incompatible). When I reset and choose this option from the menu, I get the same programmer not responding issue.

Thanks

Any firewall or PDA sync applications running?

Windows Firewall was on, but turned it off. Still doesnt work. No PDA sync either.

Do the new Arduino version & USB drivers definitely work with older bootloaders? I used an older version of the software (version 2) and the uploading worked (from a different machine).

Thanks

You might need to change the serial.download_rate to 9600 in your preferences file (this is different than the Serial Monitor Baud Rate in the Tools menu). Make sure you edit the file when Arduino isn't running. There are more details in the FAQ (Why I can't upload my programs to the Arduino board?): http://www.arduino.cc/en/Main/FAQ
