I have purchased a license for the JChem Extensions to KNIME, but I am unable to contact the server to download and install the extensions. Is this possibly a version mis-match? I am running KNIME version 4.0.2. Thank you.
EDIT: I contacted the New York office of ChemAxon. They confirmed that the link to the server in Japan is outdated. Nevertheless, it is possible to install the nodes via the Community link and activate them with a valid license.
