I have never posted here but I have to correct this stupidity being spread by Kiwwa.
I have never used my install DVD. I torrented the UK copy of the collectors edition and I live in NA. I also gave that copy to a friend of mine. I used my NA key and he used my NA buddy pass key and we both have been playing with no issues.
Excuse you, I'm not spreading stupidity. I was sharing what happened to me when I gave my buddy pass code to a friend faraway. Way to be rude.
Oh, excuse me. Technically you weren't being stupid. You were being ignorant. Ignorant to the way computers work.
Every single FFXIV disc is the same data. The hash signature matches on every version. They are all identical discs. You made an incorrect assumption that because your friend's disc didn't work, twice, that it was because of some kind of arbitrary DRM procedure encoded on the disc. You were wrong. This is not the case. Either there is a problem with your friend's computer or the software he has.
Research the case before using your own misconceptions as an example.
