This is the second time my launcher gets these stupid errors upon SE attempting to fix the servers. My launcher downloads the recent launch, I put in my password and get this

-- "Checking FINAL FANTASY XIV: A Realm Reborn"

-- "Unable to complete version check. 30410, 30607, 20457, 409"

This happened to me before, and the solution was to get the correct and most up to date boot folder. I do not know why my boot folder is not updating properly
