Проблем с Ардуино

Здравейте,

Нов съм във форума и не можах да намеря отговор на моя проблема, може би не съм се ориентирал както трябва с търсенето.

Имам проблем с ъплоуда на Ардуино платката. До преди седмица всичко си работеше и от днес се появява следното съобщение:

Problem uploading to board.  See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

 

На три лаптопа се  появява същото. Деинсталирах IDE с тотал ънинстал, качвах го пак, няма разлика.Пробвах с 3 платки нано и една уно 

няма разлика. Моля да помогнете защото ми трябва да правя термостат а вече нямам време.

Благодаря предварително.
