look closely at that Server= string. That isn't what you used. :-)
I think your mojo connection string should be
<add key="MySqlConnectionString" value="Server=mojofpna2.db.5138866.hostedresource.com;Database=mojofpna2;Uid=mojofpna2;Pwd=Hxxx9" />
Put that in your user.config and then open and save your web.config.
HTH,
