As its saying, the script pol/pkg/systems/attributes/hooks/vitalInit.ecl isnt found. If you have a vitalInit.src in that path, compile it and make sure all the rest of the scripts on your shard are compiled.
Usually you don't compile a specific script, you run ecompile and it will compile all updated scripts.
Open a command prompt and navigate to your POL root directory. This is easy if you keep POL somewhere close to your root drive. Ex: c:\pol
Now type: scripts\ecompile
And wait.
This will run ecompile.exe in your scripts directory. Alternatively you can use the StartHere.bat provided by Austin (if you're using the newest distro).
