Plugin broke widgets

Hello

I installed the plugin as instructed. It worked fine for a while and I was happy. But then… when I tried to add a 2nd sidebar to my theme with the plugin, everything broke. Now when I try to move my widgets on the widget control page, they won’t move at all. I can’t add new widgets to my page nor remove any. I can still modify the widgets that I already had activated. When I try to drag a widget from the available widgets box, the text of that widget stacks up to the top left corner of the box. If I keep trying to grab widgets, all the text just keep stacking.

I tried to remove the plugin but that did no good – still won’t let me move my widgets. So… any suggestions how to fix what ever the plugin messed up?

Here is a picture of the problem: http://i49.tinypic.com/zvwz0x.png
Edit: Also note the inactive widget areas – can’t remove them either.

Edit: Re-installed wordpress – still no joy.
