Problems with Pricing Table plugin

My Pricing Table plugin does strange stuff. Fist of all it won’t update. I am at 1.3 and my wp install keeps telling me there is an update to 1.4. But even after updating i am still at 1.3 and the update notification doesn’t disappear.

Today i noticed that clicking “submit listing” results in a redirect to a site that shows me advertisements for 5 seconds and than i can click through to the submission page. Sounds like a hacked plugin. This is resloved now by removing and reinstall as far as i can see. But something is going on…
