I installed a multi-platform version of Lightroom 5 onto a pc, and I have recently switched to a macbook air, so I tried redownloading the same Lightroom onto the mac, and it will go through the installer and everything, but after I go through the basic introduction (terms and agreements, etc) it stops, and I cannot get it to go any further than that. PLEASE help me, I tried calling multiple times but to no avail
