Meta Trader 4: Connection Problem

 

I have a connection problem with Meta Trader 4 Platform, I have 4G LTE wifi internet connection  and when I open the platform it doesn´t connect, the connection bars on the right hand in the botton activate but they begin to desapear and it says COMMON ERROR. I have this problem since october 14th or 15th.

I have this problem with all brokers where I have an account, real or demo. I instaled the platform in another computer and the problem continues.

 

Please help
