I echo what the others said. You did nothing wrong.

To answer your question regarding why you feel guilty, when you are used to doing nothing in situations like this, the one time you DO something and it turns out badly, you subconsciously blame yourself for the bad result. You need to remember that your part in it wasn't the bad part. So you have nothing to feel guilty about. Just because the end result was not good doesn't mean you are guilty of the end result. So, nix the guilt, girl!
