MiKTeX and proTeXt ⇒ No execution again

[fallou]

Hello everyone,
I installed Latex and it is working fine for a while and then I was getting this message after each execution:"you are attempting to make a Latex format from a file that is more than five years old." I google it and someone suggested that I remove the Miktex 2.8 and install the 2.9 one instead. So I did that and now it is worse, it just displays: " the system cannot find the file" . I have tried to add a key named runonce under Current version but it didn't fix it (I was told to do that also). I badly need help. I am looking forward to your suggestions.
By the way it seems that its because I didnt update the editor to point to the new version. Could you please tell me how to do it.
Thank you in advance.

First of all check if the installation of the new MikTeX version is fine. Start TeXworks, enter

Code: Select all

Code, edit and compile here:

\documentclass{article}
\begin{document}
Test

Run LaTeX here

select "pdfLaTeX", and press the green "Play" button. Do you see the "Test" on the right handed output pane?

If yes, the next step is getting (La)TeX work with your editor. If not, the installation needs to be fixed first.

By the way it seems that its because I didnt update the editor to point to the new version. Could you please tell me how to do it.

It would help if you reveal what editor do you use.

Thank you for your time.
No I can't see it, there is no excution at all. It only says that the system cannot find the specified file. I am using TeXncCenter as an editor. Now I even have problem reinstalling MikteX because I cant delete the MikteX file in Program Files. And it displys a message saying the directory in not empty
Any Suggestions?
Thank you again
