Google Adsense changed

Edit: Google sent me a mail today, saying I was yelling at my visitors to do stuff with ads. How bollox is that? Must be one of their heuristic filters gone mad. Anyway, I changed potions of the site, hope this helps!

Google Adsense is taking the piss at the moment, that is why I changed the layout once more. See the images attached below.
Update: I changed the 468×60 banner to 336×280 in order to not break the layout for visitors surfing at lower screenresolutions (below 1024+). I use 1280×1024 if you wonder about the screenshots.

Before (three column layout)

After (two column layout)

Current layout (two column)

Internet Explorer renders it like this:

Update: The new ads are performing very good. In contrast to the mere $3,02 I made yesterday (no kidding), I already earned $7,64 today. Yay for some server money!

My website is hosted on a virtual private server by zone.net and costs $65 a month. If you want to help me fund it please donate some money. Thank you a lot!
