Windows Firewall blocking Fileserve

Hi, l'am having a problem,which is,l can't download anything from file sharing site Fileserve if Windows Firewall is on,if l turn it off the it works fine.

And only seems to block Fileserve,Rapidshare,megaupload,Filesonic & depositfiles all work with when Windows Firewall is on.

How can I prevent windows firewall from blocking Fileserve.

Thanks

Have you tried restoring WF to it's default settings?

Control Panel > System and Security > Windows Firewall > Click Restore defaults (Left hand list)

Tried it,didn't work.

thanks for response
