Please be careful with the wording in your error messages. Are you getting "you are not authorized to use this functionality" from FR Studio? Typically if you apply updates to the server side you need to have the same updates applied on the client side too - since you just patched FR from the server side, I bet this is the issue.
Try to run the FR studio from the server and see if the message appears.
If you have just applied a patch you can try to apply the patch to the client side too. If you want to just try and get it working, in the patch there is a "files" directory which contains the updated files, you can copy that over top of the client installation (making sure you have carefully backed up the existing files) in order to apply the updated files to the client installation.
