I have added uloz.to to the project, because it is as of this moment the main domain and it didn't work (likely culprit of #19, i got a similar message).
I have also modified the host file to use all three domains. Thanks to that download station will recognize links and the downloaded file is a desired file instead of a download page.
There was a bug with passing wrong parameters to a function (free download only)
I have removed request library from package postinstallation script, because the node service no longer depends on it.
