I got my new MB two days ago, but I am having problems with iphoto. I had uploaded some pcitures yesterday and day before. I looked for software update and updated whatever it showed should be updated. Now when I am looking at my iphoto its all empty everything is gone. However when I go to the Mac HD and click on pictures and then on iphoto library and click on Originals there is another folder called 2007 when I clicked that it had folders called Roll1 to Roll 123. When I clicked on any of the roll it showed me a single picture under each of the roll. The pictures are the same that I had transfered. I don't know why this is happenning should I take it to the store. I also did a firmware update yesterday when it asked me to do after the software update. I then shutdown the Mb and today morning when I opened iphoto, everything was gone.
