Imovie

Hello fellow apple users,

I had to redownload my OS and all my software recently as the mac became stuck in a loop after the mavericks download. I am just trying to put iphoto and Ivideo back on to my MacbooK. I may be really stupid here but I go to the app store select the app I want, the blue drop down menu says accept I click that, then the ID pasword and email box come up and I enter in the correct information. After this is accepted the password box goes away, normally the download would start here but in my case nothing happens. Please help

Thanks
