My computer didn't fail after all. I can breathe a sigh of relief now.
I have finished editing Restraint. The original was edited by myself. Since Susan, my editor, came to me after Restraint was already released, I didn't ask her to edit it. But now she has looked over everything, and I have already made the necessary changes.
While I have uploaded the files, it will take at least a day for the new copy to upload.
For those that have already downloaded it on their nooks, I was told by Barnes and Noble that when your nook has to redownload it (from not using the file) it automatically updates to the new file. Smashwords always makes the new file available to people who have downloaded the original. As for Amazon, please contact the customer service with that question.
