I didn't make myself clear enough, and I have confused the readers here. I was in the same situation a year ago, my referee didn't have the time to edit a letter, and I was told to modify it myself to save time. I was permitted after waiting for long without any reply. It is possible to modify someone else's letter that is if permission is granted.

If you think you can modify it, the typos, it is advice able to do that. She might not have the time editing, and it may be insulting saying there are errors. She took time out to write the letter. It's up to you to modify it if in any way possible for you to it.

Thats a good idea, however, it depends on her friendly nature. I think you might get an expert to help you with that. There are specialists when it comes to recommendations, they can help you with modifying the weak one, check for typos. They have been of help to me. That is if the time is almost up and there is a delay in getting a response from her.
