I may not have to worry about my laptop dying because I just wounded it.

I upgraded to 'Windows Whatever ' a couple of years ago and Outlook has not worked since then. I need it. I thought maybe the thing that said 'make it something work with earlier versions of a program' would fix it. OH NO NO NO NO. I got to make windows OFFICE work in earlier version or something and clicked it before I thought. Whole thing shut down and was hard to get back going. Its slow but I don't know if it will speed up after it gets going? SYSTEM RESTORE??? I don't like to do that very much but don't 'think I want to run old version of Office? Or do I even know what I am talking about and everything is ok? haha

thanks,
