Problems deploying SSRS 2012 SP1 to SharePoint 2010 SP1

Hello, 

I am having issues installing SSRS 2012 SP1 in SharePoint 2010 SP1. 

I am able to install the components from the SQL Server ISO and run the Powershell cmds that create the Service Application & Proxy. However, when trying to start the service, i receive the following message:

Start-SPServiceInstance : An object of the type Microsoft.SharePoint.Administra
tion.SPServiceInstanceJobDefinition named "job-service-instance-4e5d3f1d-06c9-4
e1c-80d4-ca4cc3814fab" already exists under the parent Microsoft.SharePoint.Adm
inistration.SPTimerService named "SPTimerV4".  Rename your object or delete the
 existing object.

Going into Central Administration, the SQL Server Reporting Service is always in the Started or Stopping phase.

When I look under Operations -> Timer Job Definitions,  I see the one time SSRS Service provisioning job, but it appears to never run. 

I am also able to create the Service Applications, but when i go to Manage/Admin Service, i get a 401 error. Nothing useful is in the SharePoint log that is associated with the correlation id. 

Any insight?

Thank you in advance.
