Instead of posting a question like this, go to the bug report forum and ask why it's not working. I played all night last night with many FC members. Didn't seem to have any problems there. Could be your download got corrupted during patch. Never looked, but does the patcher have a repair option? Other alternative might be needed to redownload all of FFXIV. If you do that, don't delete your old install, just move it to another location until you are sure that you need to download everything again.
