I'm having a problem with windows 8. After I verify it will not upload, in the sketch in the lower right hand corner it shows COM3 as it did when it was working OK. Can anyone help I've spent about one month with this problem. I got it to work for about 2 weeks then the auto update from MS moved something around. Now I have the same problem even after taking all the Arduino off the computer and loading the new Arduino Bata1.5.2 on. I am at a loss as to what to do now. I would not want unload W8 and go back to W7 as suggested by someone a while ago.
Thank You
Steve
