So SQ4 went awry...hanging, black screens, retester showing 0 strategies passed, yet data bank marking them all as passed, different runs on identical settings giving just a handful of trades once time, or over 1000 trades for the same strategy when running another time, completely random, cannot trust any result. On previous machine it was fine.
So figured I would do a re-install. But no option to uninstall either in windows, or SQ4 - no uninstall.exe anywhere either? Should I just delete the folder C:\SQX?
