Trying to open RME in LMS3.1 - I get HOME0004 error - unable to retrieve out-of-sync data. I have attached the RMEHome.log that details the error. I currently have the same privs that were present under LMS2.6. Note: sometimes this works, most of the time it doesn't.
Are you integrated with ACS ? This message can happen when the integration have not been properly made with ACS.
You may want to reintegrate LMS with ACS.
