No need to be sorry.
I appreciate you taking the time to help.
I deactivated the plugin http://wordpress.org/plugins/rename-xml-rpc/
Then I renamed the xmlrpc file back to the default name.
Now everything works fine. I don't understand it because it never worked properly right from the start before i renamed the file.
The mobile app seems to be working properly now also.
Could i possibly have caused something to reset once I changed the name of the file? Or fixed a bad instal in the first place?
Im totally stumped but at least its working again now.
Thanks again for the help.
