PRT loses my screeners?

[appress]

Hi, has anyone else experienced this? I'm missing version 3 and 4 of one of my screeners. 

On Friday there were 4 today only 2 😔

So, foolish me because it's happened before, should have backed up, but what the hey is wrong with PRT that user data goes missing?

I always export/save trading system and custom indicators, 

Then its easy to import them again if somethings happens 

and easy to move them  from demo to live or another installation
