For about the past week or 2, I have not been able to get my system to work. One moment the com ports were good to go on my laptop then a minute or 2 later nothing. I even uninstalled the arduino software and installed the laterst driver and nothing. i can’t get it work at all. I am really loosing my patience and would hate to have to buy another pc or laptop just for this to work. If someone can please pm me and help out that would greatly be appreciative, because at the moment I have a very expensive paper weight.
