Ads crashing game

Has anybody had this problem? I've spent nearly a week trying to fix it. Cocoon.JS canvas+ crashes with the cocoonjs ads. Intel XDK crashes with the admob ads. But the ad free version runs like a king.

Regular banners ? or video ads ?

I had some issues with video ads some time ago, not using them solved it for me there

I think I did a bit of wrong timing, and could have done more wiser using the video ads before the game engine events kicked in.

Lately I have been using the iframe approach and implement sdks from banner suppliers by means of a simple html file fetched with ajax from my server.

update you sdk
