Strategy Tester no history data

[Jan Hendrik Jordaan]

When trying to run the Strategy Tester I get an error message 'TestGenerator: no hostory data'. I've completed numerous of tests in the past but it stopped working all of a sudden and cant seem to fix it. Anyone got any advice or known issues regarding this please?
