Hi FKMA,
If you are having problems with server errors, may be some kind of protection not allowing you to go direct to a page.
If so, go to the main page (forget the directories after the first "/") and try to get the internal pages by ther options inside.

My keyboard is an A-90 not the EX version.
I'll buy the expansion board quite soon and will get in contact with you to change patches.

Bye,
Fernando Justo
