We traded private messages a while back regarding this topic. Since ads were no longer on my forum I figured things had worked themselves out, but I guess it wasn't quite fixed.
My forum was a pay forum, but there have been problems getting payments to go through with World Pay so ads are now back on my forum.
I definitely want to use the pay service, but I'm just not sure what to do next. Let me know and I'll try and get it sorted straight away.
