Problems uploading sketch

Hey there guys, hope you can help me.

I am currently having problems uploading a sketch to my arduino (I am currently using Duemilanove on Windows Vista home basic, using Arduino IDE 0012).

Everything checks out ok, the bootloader works fine, per the instructions on the troubleshooting page, it powers on fine, Windows reads the board, and tells me the correct drivers are installed.

I hope this is enough for someone to help me.

Many Thanks

Swirl

What happens when you try to upload? Have you tried disabling firewalls / security software?
