v15 error Bewertet mit 5 von 5 Sternen

I have been collecting data with this program for about a year now. Everything has worked perfectly until yesterday when I discovered that data from the end of May upto now is missing.
I have Firefox 15.0.1. The files can be found in the scrapbook data folder, but they do not display in the search tree and I am unable to import them - an error of Can't copy files appears.
Is this problem related to the v15 firefox and are there any solutions?? Thank you.
