I wish I could help you get it back how it was, but I can't, your application software is gone. If you don't have the original installation discs for it, then you'll need to go shopping.

Computers teach is in rather brutal ways the importance of an uninterrupted power supply, good data backup habits, etc. I'm sorry you had to learn this lesson the hard way! hopefully someone else reading this will be able to prevent a similar thing happening to them, because you posted this.
