I can't upload anny sketch to my arduino uno.
This is the error:

Thank you.
It worked fine before. I have windows 7 as operating system. Reinstalled drivers and program. I use the right port and selected the right board.
First i thought i had a bad bootloader problem, so i bought a new ic with a bootloader on. It didn't solve my problem.
I tested the echo. Nothing happens. RX and Tx don't flash at all. Not even when i upload a sketch. Whats wrong?
Is my arduino uno broken? :~
Thanks for the help
