Recovering the lost optimization results

Michael Reuben Msidada  
I have been running an optimization on Strategy Tester for a week and then a pc become responsive I restarted it but the test result which was supposed to be complete is not found. I only see the entry on optimization history. I try to start it hoping it will resume the optimization or display the results but it started from beginning. Is there something I can do to recover the optimization results?
