My ads don't show up

[Salvatos]

Starting today (I think) my ads stopped showing up. All the rest of my pages works perfectly, but although the ad codes are there, nothing shows up.
I'm using this code:

<DIV align="center">
<!-- Ad Code -->
<script type="text/javascript" src="http://x10hosting.com/adserve.js?salvatos"></script>
<!-- Ad Code -->
</DIV>

As provided on x10's website. Is there a problem with my code or would it be coming from the server? I wouldn't wanna be suspended for absence of ads, as the script is in the pages' code...

Advanced ads aren't being showed at the moment.
If you see that your ads are not showing, please check this website: http://fedlerne.x10hosting.com/
If the ads doesn't show in that website, then it's not your problem.
If the ads do show in that website, it's a problem of your website, and you need to fix it.
