I'm having a problem MSN can you help?

I'm not sure if I'm posting this in the right place but I'm sure that someone will move it for me if it ain't.

The problem is this.............

I cannot open MSN. When I try the following message pops up...........

"Sorry, we are unable to sign you in to the MSN messenger at this time.
Please try again later.

MSN messenger has made several failed attempts to sign you in. Your firewall may be blocking Messenger from connecting to the service. Please review your firewall settings. See the retailers instructions for more information."

When I do the troubleshoot is says that its the 'host file'

"Your hosts file contains MSN Messenger related entries which may interfere with name resolution."

Anyone know how I can resolve it?

in explorer clok tools
view
mark - show hidden files

then goto

your hosts file is here
Windows XP = C:\WINDOWS\SYSTEM32\DRIVERS\ETC
Windows 2K = C:\WINNT\SYSTEM32\DRIVERS\ETC

open it in notepad and delete any lines with msn or microsoft init.
then save.

iof that dont help then uninstall messenger and reinstall it
