You will need Lucid Player to use the Lucid keys. You can obtain this for free from http://www.lucidcentral.com and you need to install it before you try to download the keys. Remember, Lucid currently only works with Windows style machines. The X-ID version will run directly through the internet without any local software on any desktop machine linked to the internet. The XID versions are still under development.
