I have been attempting to get L5 to load on my MBP for the past three days. I download the .dmg, drag the file to my applicaitons folder, open the application and then I get a crash report. How many times do I try before I qualify for the status of repeating a failing task over and again expecting different results? This is very frustrating because I cannot even go back and find my L4 so I can study for my message on Sunday!
