I broke my Template

It's like the DNA of my blog has been altered. The effect only shows up in IE, which I only use occasionally since Firefox is so much better. Luckily I loaded my blogger page with IE or else I would have never known. Here is what happened: I wanted to get rid of the word 'archive' which was left over even though I turned archiving off. So I edited my Blogger template by deleting some lines that put that word in my blog page.
When I republished, and then checked my page (using Firefox) all was well. So why is IE's interpretation of my blog page different than Firefox anyway? Damn Explorer!
Now I am trying to restore my template so it works with IE. So much fun, oy vay.
