I am new to mIRC and i can't connect to any server. when i start the program.

I just installed mIRC and am using windows vista. Everytime i click on a link it sends me a message stating the following:

windows cannot find 'irc://irc.***********.com' make sure you typed the name correctly and try again.

after this, once i click the "ok" another window appears stating the following:

Internet explorer cannot open this helper application for irc://irc.***********.com. The protocol specified in this address is not valid. Make sure the address is correct,and try again.

Please help me with this.
