Arduino IDE wont load to Mega 2560 it gets half way through the compile and upload, then says com X is already in use?
I am running win 7 and it doesn't matter what the baud rate it set at for the port. There are no other programs running to lock up the port and only usb plugged in is the 2560 and the keyboard. Someone please tell me the secret. Thank you in advance! Oh and it doesnt matter what version IDE I use either.....

Where do you set the baud rate?
Is it a genuine Arduino or a fake clone?
I doubt it made it half way through the upload - it either fails right at the start of the connection or not at all.
