Error : avrdude: ser_recv(): programmer is not responding

Hi,

I have 2 arduino cards and from the monday the twice does not work. When i do an upload, the RX led lights but not the TX.
For each programs i compile i get this error :

Binary sketch size: 896 bytes (of a 30720 byte maximum)

You've lost me there. But from your mention of Monday are you saying it worked on Sunday? Or what?

Have a look here, same problem.
