Adding banners to an OpenAds campaign

I am looking to place ads on a website that I am working with. I have installed OpenAds 2.0, but I am having problems in the initial part of setting up my campaign. Everytime after I try to save a banner to my campaign under the "banner overview" tab, it still says "no banners defined for campaign", despite the fact that I have filled in all the fields before saving. A couple of times the banners have saved properly, only to disappear in front of my eyes minutes later. I have read of similar accounts on web forums, but no solutions. If someone already familiar with OpenAds could add a few banners to my campaign, and then send me an email explaining why they weren't saving before, that would solve my problems. ## Deliverables 1) Save eight Validclick ads onto an OpenAds campaign. Four HTML ads sized 728x90; 468x60; 120x600; 160x600; and four text ads of the same size. 2) Ensure those ads stay saved for a 12 hour period. 3) Send a brief email saying how it was done, and what the problem was. ## Platform Valueclick/Openads
