After updating to Notepad++ 6.7.4, it asked to update the plugin manager to version ~1.3 or something. The update failed various time (with N++ being started in Administrator mode) and then left me with a "blank" configuration.
Thanks to the new "snapshot" feature I had unsaved files and modifications. How can I recover them ?

Thanks & Great work !
