Any help would be highly appreciated! Thanks

Answer 1

(this would have been a comment but comment formatting is meh

To do this:

cd node (your node dir)
git tag (see the list - I believe 0.4.11 is last marked stable)
git checkout v0.4.11
./configure
make clean
make
make uninstall
make install

Then npm install express.

That will reset you to 0.4.11 and you should be ready to rock.
