embaressed messed up HBC install

I copied it over first and right when I hit copy I remembered about playing game first.
The same does not show up in the save menu but says when trying to copie back over that it is already their.
Did a format and did not change anything did I just really messup?
I fell like such a n00b, message never try moding with no sleep.

also should mention this is friends machine that we bought night before last, maybe it has update 4.0?
thanks for any and all help.... I'm so humiliated.

I'm afraid you need to give us a TON more details. Think of going through your entire post without using the word 'it' or another pronoun.

Try using bannerbomb instead of the twilight hack.
