Creative Cloud running insanely slow on brand new iMac

I just bought a brand new iMac computer two days ago because my Macbook Pro crashed and had to be sent to Apple for repairs. I downloaded Premiere Pro and it took 10 minutes to open, and then everytime I click, it takes about a minute to catch up with me. I've restarted the computer multiple times, and I've even tried using it in safe mode but it doesn't help. My computer has 8GB, but according to Adobe's website, this shouldn't be an issue. I need to be able to use this application for both school and my job and I'm running out of options so any help would be greatly appreciated.
