Purchased advert not running?

Hi, I was told to post here by a moderator. I purchased in advert on the 9th september, but it doesn't show any impressions since. Any idea why?

It looks like there has been something off with the priority and configuration of your ad. We just made a few changes. Let's see if it makes an improvement within the next 24 hours.  

First, an ad running "standard" that has zero restrictions will show up about 300 impressions per day - because there are a lot of ads running.

Your ad has restrictions for the country which will cut the impressions in half.  Further, you limit showing the ad to just those threads in a few forums.  That will slow it down much more.
