KEGG is no longer freely available. They switched to a service fee model.
Fortunately, there are alternatives. WikiPathways is free and licensed under
creative commons, so it will always be available for free. These pathways
are built into GenMAPP-CS (the new version of GenMAPP) by default.
I recommend checking out the new version and the documentation there:
