PLEASE HELP! Cubase 7.5.20 will not open .bak files

Thanks for the replies.

The next previous .bak file seems to work ok. But for me, even 10 minutes = a lot of work done!

I have been working with DAW’s for years and so regularly save after most edits/work. But sometimes it takes about 10-20 minutes when creating a new sound or part and then I haven’t saved and then it crashes. That .bak file is supposed to be my saviour! Every time it has happened the most recent .bak file gets corrupted somehow.

I have been using Logic for 22 years and with recent versions it always saves as you crash so you lose absolutely nothing. I’m trying to switch to Cubase so decided to do this cue in 7.5.20.

Not a wise idea so far.

Is there no way to fix the .bak that’s probematic?
