Adsense link units not working with Quick Adsense

Hello,

I’m approved for adsense and have three widget ads running.

I’ve tried to use quick adsense to insert a link unit at the bottom and in the middle of the homepage and it has not worked.

I’ve re-installed the plugin.

I’ve waited 48 hours in case of a delay at google’s end.
Any advice or any other plugin that can be used to place link units where you want them instead of same place on every page?

Thanks
