I click on my calibre icon to open up calibre but nothing happens.
I have also tried right clicking and pressing open but again nothing.
It worked ok earlier in the week and as far as i know all i have done is added some more books to my library of over 7500.
As far as I can remember I am using version 5.33 and i'm using Windows 10
Can anyone help as would be shattered if I lost my Library??
Thank you
