Well, it seems i've found the issue. There was a plugin.exe from adobe flash player addons running with a 99% cpu usage. I tried to kill it and run FFXIV and it loaded perfectly. After uninstalling/reinstallig adobe flash player, that plugin.exe is gone and everything is loading without any issues (for now). I've been playing for 3 hours loading all maps in around 4-5 secs, so i think is fixed :3
