Please try with the latest Version 312S of QuantTrader available in the forum or below. These errors came from previous versions which had a bug with renaming/duplicating/deleting strategies. This should work now. You probably will need to begin with a clean QuantTrader.ini file as errors will not be fixed automatically. However I can do it by hand if your ini file contains valuable work.
