Ok, I will take that into account, but what could cause the problem that i can't upload a sketch or the bootloader?
Well, the com port appears. If I do not connect the arduino, the compiler returns 'avrdude: ser_open(): can't open device "\\.\COM3"'. So my arduino connects to my pc. It start compiling and uploaden so the com port is in use. If I want to try uploading again, I first have to disconnect my arduino from the usb port, otherwise it says 'com port in use'.
Unfortunately it didn't seem to work. Still the same problem. When I press shift+ U, your ide asks to apply a fix and afterwards it's says 'Done Uploading' but nothing has happend.Although I like your work I like the button in the taskbar.
No, I can't upload anything. It starts uploading but does not finish.Also the leds TX and RX don't blink, like the normally do when you upload something.
