I have exactly the same problem. When I try to click SAVE it complains every time and MT4 is not running. I too managed to confirm that it was Tockstory itself that locked the file and managed to unlock it with a that mentioned tool, and then I could save the file. But, now the file seems to be corrupt. When I run my backtests on that one timeframe I changed they are super fast and my model quality becomes N/A.
