Needed to reinstall Creative Cloud on Mac OSX, now it crash at 50% during install.

I downloaded CC from adobe and hit the install button but it crashes at about 50% and give me the same error message, that there was a problem installing CC, please download CC from adobe, but same thing happens?? I tried it several times with no results, all of my adobe apps still work PS, AI etc... but I just can't get the Creative Cloud running again to get new updates and Adobe apps.
