Uploading error

Hi everyone!

I am getting this error everytime I try to upload some programs to the Arduino.

I compile them and i get no errors but when I'm try to upload them it takes a while and then i get that error.

This happens even with the built in examples.

Eventually my arduino works well but i don't think it's normal. Any suggestions?

Thanks a lot!!

Please don't use stupid pictures if you could have just copied the error message; place the cursor in the output window, scroll up and select all text and copy. Paste the result here using code tags

[code] your error message here [/code] will result in

 your error message here

Oh, and I'm sorry but have no idea how to solve your problem.

Agree. Don't use pictures for text messages.

Checksum errors usually means that the USB cable is bad. Try other cables and other USB ports.
Seems like there might be issues in general with machines from around 2010.

Thanks I'll try to check it with another cable.

Just for the record.

I've installed the arduino 1.6.5 rev2 (the one I was using before) and it works good again.

It seems there's a problem with last version...

My arduino board is a mega btw.
