Guild database problem?

[Terazel Tenjin]

Don't know if anyone else besides Masa that's experiencing this, but my account can't set nick or do anything in guild management after I have been added. Masa only had this problem with one guild (LOA), while I seem to have the same problem with Tenjin and VV. I am guessing it's an guild DB problem, since my account can still use Vigilant Knights (added and set nick a LONG time ago, probably last year). Does anyone else have any ideas about what's wrong and/or how to fix it?
