Issues view Ads on my own site?

I just had some ads installed...similar to your typical pay-per-click set up.

My problem is everyone can view them but me? I mean I can view them on my laptop but that is it. The desk top is a blank as if nothing was ever installed. I tried updating my flash image and everything worked for a few minutes. But now it's back to nothing at all. Is this typical, is the owner not allowed to see the ads?

I'm also using firefox and XP if that matters.

Thanks,
Ray

 

Honestly I don't know enough about firefox.

 

Can you see other Flash things? Maybe your plugin needs updating.

 

I can see everything just fine but I have a plug in issue since day one with firefox. I've had to upgrade it about once a month. I did it today and everything worked great on my ads but now I can't see anything

 

It's something to do with firefox.

I completey deleted it from my system and used interne explorer. So far everything is working perfectly.
