AdToApp problem

I have been testing out adtoapp for a couple weeks now on an app that hasn’t been released yet. I noticed a disturbing interstitial ad for MobileStrike recently whereby it pops up and is impossible to close it. Clicking on the ad’s close “X” simply re-displays it again. AdToApp please sort this out ASAP. If the app was live it probably would have led to lots of negative reviews.
