Cool, glad its working.
Do me a favor and after you login to your site look at Administration > System Information and see what version of mojoPortal you have.
The reason I ask is because the current version of mojoPortal in the web app gallery is version 2.3.6.2 and it is pre-configured for medium trust hosting, so the steps I just had you take should not have been needed if you had this version. So it makes me think your host is somehow using an older version of mojoPortal and not really using the latest feed from the web app gallery.
Best,
Joe
