TeamViewer won't open on mac

Hello - I have had a mac for 4 years and always had trouble with teamviewer... I have recently upgraded to the latest macbook pro and have the latest OS installed. I just deleted everything in my computer that has TeamViewer on it... did a fresh install today again... I download it. Run in the installer... and then it continues to bounce at the bottom forever... it eventually has another icon start bouncing... and then it stops. Sometimes it opens up TeamViewer and just shows the preferences bar at the top, but nothing more. 

In my Mac Settings, teamviewer has access to everything... in accessability> it's all enabled.

Please help!!! I use for work and is such a pain... I currently use **Third Party Product** to remote into my PC to remote into my work computer...
