Cannot delete replication partner

Trying to upgrade my SEPMs to 12.1.2 and I use replication. I'm trying to delete the replication partner per the upgrade process and I get "Replication is currently running. Please delete it later." If I click the "Cancel Replication" option, it says "Replication is canceled. For details, check the log files"

I've restarted the box, the service, the DB.

Something is obviously stuck so now what can I do?

Please help! Thanks!!
