Hi Igor - I have now managed to open the file but it is totally corrupt and I am not able to restore to a previous version because there is no previous version. When I did manage to open it it only had half the photos and no time for each slide set. They were all zero. I have been trying to work with the corrupt file and deleted some slides that were causing a problem. However I have noticed now that when I "preview from this point" the music is not synchronized to the slide - the music just starts from the first track again. Very frustrating. Thanks for getting back to me - I appreciate it. PS I have tried to re-install the program. 7.5. Regards, Christine Barker
