A crashed computer!

I have two computers, neither of which I understand or comprehend!  I am trying to write a speech for Monday night and Sunday the computer crashed and died! Mark Hoffmeister, my tech guru, came yesterday and pronounced it dead and called ITOK to resurrect all the files on the second computer!  He assured me that all would be well this morning!  NOT!

Glitch!  I hate computers who don't behave like I need them to!
