ok, i had to reinstall iphoto, and now it opened fine, but all my pics are gone, so i went to my pictures folder and tryed to click/drag iphoto library back into iphoto but it wouldn't work. it just said "the following files could not be imported (they may be an unrecognized file type or the files may not contain valid data" then in a lits it names the iphoto library file. i don't know wat to do, i tried doing tit with individual pics from the iphoto library and i got hte same message, but with PDF files, that weren't orriginally in iphoto it worked fine.....i don't know wat to do
