Because you are using a network hardware lock, you don't need to have SPNSRVNT.EXE running as a service. The correct way to remove it is by going to the installation directory for RiverCAD then navigating to the directory Sentinel\Server. For Example my RiverCAD installation file is C:\RCAD, so I need to go to C:\RCAD\Sentinel\Server. Then run the file "loadserv.exe" to open up the SuperPro Service Loader program and press the "Remove Service" button in the middle of the screen. This should remove SPNSRVNT.EXE as a service on the computer and you shouldn't receive those errors anymore.
