Not Saving User Details in Auto Signature

Hey there, great app.


I have a slight problem with using the MXHero Auto Signatures. When I try to edit the user details in any way, and click "Save Changes", these changes *aren't* saved, and do not come up in the signature. As expected, when I go back into edit the user details (any field), it is exactly how it was before the edit happened.

After I try to save the changes, I get no error message and it says "Successfully Saved" or something like that.

Am I missing something? How can I get these changes to "stick"?
