I am trying to use the Achievement Unlocker and I keep getting an error message. I have uninstalled Horizon and downloaded the most recent Horizon update and I still get that message. Has anyone experienced this? or know what is wrong? 
What is the error message you are receiving?

I actually ran into this problem previously so don’t be worried. Simply delete your profile off your hard drive or USB and recover your profile and try again.

This worked perfectly. Thanks.
