Resolution:

1- Deactivate ems probe
2- Deactivate trellis probe
3- Delete the ems probe and delete the entire ems folder from disk
    There is a small risk that some alarms or synchronization with Service Desk may be lost.
     However, in this case, the EMS probe is not functional anyway.
4- Deploy ems 9.01 probe from the archive
5- Activate trellis probe and ems probe
