Something wrong with Network Connections

Icons in the network connections folder are missing. Besides that the connection i used is disabled and i can?t enable it, so i can?t connect to the internet(and it makes fixing problem somewhat harder because i have to use another computer)I found one topic about this problem and did everything that was told but it didn?t help.

I don?t know what to do.
(i?m new here so i don?t very well understand this point system. I hope 150 points is good enough.)
