First (1 use case - the more simple)
I do backup every minute to preserve my data. So, now, you tell me that may be a problem. ok but I've tried before to do it every 2 hours but the result don't change. My data is lost in grindstone (visual) - i don't see nothing of my track activities...
NOTE: If i open the last backup file in notepad i see all my data in your format!
So: every time, for example, i shut down your program correctly (by the appropriate button) or NOT correctly (by kill by task manager to simulate Windows errors), the next time i open it i have ALWAYS the same problem that my data is lost because grindstone tell me that every backup is "broken" and i must contact epiforge to resolve this case.
Also if i close program correctly and shut down my computer and rerun grindstone 2 i have the same problems seen before....
