The Swedish translation for jv16 PowerTools 2011 has issues, so Service Manager Optimization feature can not be run properly.
It's due to an incorrect line in that translation in the section .
I have fixed that error and in attachment you find the fixed language file concerning the Service Manager problem.
After unzipping the file place Swedish.lng in the subfolder "Languages" of the directory where jv16 PowerTools 2011 is installed instead of the former incorrect file.
