"No connection" error

Hi guys.
Since I started using MT4,after I download something with utorrent,the MT changes the connection status speed to around 200/2 kb and when I try to place an order,it shows me the “No connection” error.To make it work again properly,I must uninstall and install again the MT4, but after I use utorrent again,it happens the same thing and shows me the same error.
What should I do to be able to use both of them?

You downloaded something? What is that something? Did you download MT4 through Utorrent or some other file that affects your computer? Based on what you give us I cannot help you.

[B]I download my MT4 trough my broker site,that something wich I download trough Ut. is usual stuff,like tv series.[/B]
