WampServer

Ok here is my problem first off I downloaded WAMPSERVER from wampserver.com which comes with php5 mysql and apache2 all in one bundle installed everything to c:\web server told it that site root is c:\web server\www which i have an index.php file in now then windows asked me to unblock apache2 which is the only thing it asked to unblock just to let you know ... i also have a dns server that routes vampzfreak.com requests to my ip (which is dynamic and i update every time i reconnect) the site is only available when im online so i get online update dns servers and try going to my website ... then it just hangs at "waiting for vampzfreak.com" till it gives up i quite wampserver switch to a different http server which isnt a free one... and is a trial one.. its only like 92kb in size and works! and id rather use a more secure one that wampserver provides i downloaded and it works perfectly .. what am i dong wrong?
