cTrader lost all my drawings (and workspace modifications) for the second time

Hello. I came to write in despair almost. This is the 2nd time ctrader is losing all my drawings and work in my workspace. I saved it at least 20 times yesterday at various points inside the day. And ctrader confirmed (via the notification window) that the workspace is saved. I closed the program last night and today the workspace has reverted to maybe a week ago. All work gone, this is hours and hours of work and analysis. How can we have faith and rely on the program when we cant know for sure that our work is safe from modification or erasing. Is there a local file we can back up ourselves. If not, why not? I see there is no auto-save feature. Not that it would help, as I saved the work myself and still it vanished. A help here would be greatly appreciated.

The last time was last weekend, again. Not sure if it is related or just that I rebooted computer, but same thing had happed and all work was gone. I was hoping this was a once off but right now I am feeling I cant rely on this. And I need to rely on it as I will shortly try for the ftmo challenge.
