Well I'm not happy

I decided to change my layout (as you can see) and I saved all the html language for the old one in case this didn't work correctly. I thought that would be okay...not...I have lost all the info on my sidebar. NOT HAPPY! I can't get it back. I've tried for an hour. You would think that the info would just transfer over...yeah that would be too easy. So now I have to figure out a simple way to put all that info back in....like I have time for that!

Anyone know how to remedy this problem for future reference? Or am I stuck forever with the layout I choose?

This is how I feel....
