Article.cls not found

[mcai5]

Sirs:

I recently joined TUG in order to find a solution to the  ‘article.cls not found'  problem.

Today I downloaded and installed a new copy of the complete TeX system, after deleting all traces of it yesterday.

The problem still remains, as I observed when I attempted to compile a paper I am writing.

Where can I get a copy of ‘article.cls’, and how should I install it so that TeXShop can find it?

Respectfully submitted,
