I'm using LyX for some Maths coursework, I've installed LyX with MiKTeX twice now (re-installed after first encountering this problem) but I'm still getting the same problems.

Basically none of the classes it uses are available. When I load it up it first pops up saying:

The selected document class Article (Standard Class) requires external files that are not available.

I am sure it's at least tried to install these files as I saw it come up in the installer's output.. Is this a common problem that anyone knows how to solve?

Thank you.

I've managed to seemingly fix this myself.

I just ran:

Tools -> Reconfigure
