There's a "Silver" and a "Gold" version.
It simply means that the version labeled "Gold" is a second edition (or third) and the one labeled 'silver" is the first edition (or the second).
Sometimes the content can be different or a second or third edition might even have an extra CD.
I will upload the Silver edition first and then the Gold edition.
Don't know if it will be ready today (ripping, converting, making an archive).
