most likely cannot......
try start -> run -> cmd
1) ping google.com (if no ping reply at all you can give up now)
2) telnet pop.streamyx.com 110 (you should see +OK TM Net POP3 Server, if don't you can give up now, also)
3) if still insist, subscribe 3 days trial and .......... good luck
btw, post the screen of ipconfig/all will help
