Can't download- Need Help

Hi..i am new here..and i am having trouble using bitcomet on my laptop. I tried to download a file and i get no seed and no peers..but when I tried to download on my PC…I get a number of seeds and peers..

Does anyone know what is wrong with my laptop or how i can check the problem… do i have a firewall or something which is not allowing other ppl to get through.. if so..how can i check it..

thanks..
