Ad shares a similar Display URL

am I crazy or google messed up

[nikonick]

Hi guys,
The problem occurred shortly after I started advertising in Adwords one of my old domains. Most of my keywords got inactive because: "Ad shares a similar Display URL with a competing, higher ranking ad". I believe I know AdWords quite well, still don't know why this happened. I'm absolutely sure there is no other adwords ad with the same domain name. At the moment I replaced the domain with another one (just the domain, not the rest of the url) the ads showed. Is there a chance Google doesn't like the domain name if it has bad history?
cheers

By inactive you mean doesnt show ads and not an inactive status right?

Also while the ad diagnostic tool is better than before, it still isnt perfect, so if it says that the domain is already being advertised, this could be an 'error'.

Is there a chance Google doesn't like the domain name if it has bad history?

I have not heard anything of the sort.

yes, keywords status is OK (active), but not triggering any ads
