nodemailer node-email-templates, no such file or directory errors

I want to use email-templates package in combination with nodemailer, but am getting errors about the template files not existing. I have tried both absolute as relative paths, all to no avail. Finally I decided to try and get the example to work, but still no luck. Here is what I did:

Download and extract zip file of node-email-templates-master and:

cd node-email-templates-master

npm install

npm install nodemailer@0.3.27

cd examples/nodemailer

node index

I am getting the same errors as before:

fs.js:338
  return binding.open(pathModule._makeLong(path), stringToFlags(flags), mode);
                 ^

I am running node version 0.8.12

Installing the package via:

npm install email-templates

and executing the example file:

node node_modules/email-templates/examples/nodemailer/index

Give the same error. Is there anyone who can please help me get email-templates up and running? Tnx!
