C:\Games\FINAL FANTASY XIV - A Realm Reborn\boot\ffxivboot.ver

C:\Games\FINAL FANTASY XIV - A Realm Reborn\game\ffxivgame.ver

My ffxivboot.ver was reporting this version number

2014.01.18.0000.0001

However my ffxivgame.ver was blank. I copied the version number and pasted it into ffxivgame.ver and saved it. I then ran up the launcher and my game started downloading a 657mb patch with February dates, so after the 2014.01.18 my version number was reporting. Once it finished download/updating these I could play.

Hope this helps someone, judging from the number of posts there are obviously numerous reasons for this error to pop.

Thank you! This fixed it for me, however my version was correct but my 'Region' was different. Had to change 0 to 3 and now it works perfect.
