I Lost My template!!!!!

UGH!!!!!!!!!!!! I hit the wrong button!
I went to backup my template and I hit save template and gave myself the blank Minima template! I am so MAD! I could break something! Okay so here is my new blog with no background no colors and no 2 side bars! UGH! I will fix it later today or tonight. If anyone knows if I can backup with an older saved version will I lose my template and widgets? I am trying to decide if it is easier to refigure out how to change the template to 3 column and change the background or if I should upload a previous version. But I think I will lose more that way! Oh Me Oh My!
