Did you load the Google Maps API with your own API key?

Update

Check out the troubleshooting page for IE.

Maybe you're checking for it too early. Try something like this:

var iterations = 0;
function check_compat() {
    if (iterations === 75) {
        alert('Failed to load Google Maps API. Clear your browser cache, open Google Maps then try again.');
        return;
    }
    if (typeof GBrowserIsCompatible === 'undefined') {
        // It isn't loaded, schedule the next check.
        setTimeout(check_compat, 200);
        iterations++;
    } else {
        if (GBrowserIsCompatible()) {
            mapReadyFn();
        } else {
            alert('Sorry, your browser is not supported.');
        }
    }
}

After that, just replace this line:

if (GBrowserIsCompatible()) {

with this:

function mapReadyFn() {

If it fails for 15 seconds, it stops trying and you get an error.
