It looks like the same MID Server service is trying to be used by two different MID Servers? Did you uninstall the first mid server first? I would say if you are going to go the route of just redoing the MID Server i would make sure to utilize the installer.bat found in the agent folder. Install multiple MID Servers on a single system

While those are steps normally for multiple MIDs on one server it can help to also make sure resources are divided correctly.

Let me know if that helps or works.
