# This script first clears the CRL cache in the event a proxy CA, internal CA, scanning tool CA or AV CA gets trusted for 
# something it shouldn't and your mac won't accept the genuine certificate.
# After clearing the CRL cache this script shreds the App Store caches - probably restart after and try downloading from the 
# App Store again.
# If it doesn't fix your problem.... well good luck, may Google be by your side.
