Go to:
C:\Documents and Settings\YOUR USER NAME \My Documents\SH3\data\cfg\Careers\CAREER NAME
Choose patrol numer -whatever you are currently on
Open the read me file in note pad, scroll down near the bottom and you should see-
DeltaRenown=25.000000
change value back to
DeltaRenown=500.000000
Then save the file.
Hope this helps..
