Open up the Creative Cloud App, and uninstall AE, then re-install. If you also have Premiere Pro make sure that the versions are compatible.
If you have any other problems let us know.
It seems to have fixed the Dynamic Link Server error pop up, But AE 2017 still hangs when exported to media encoder or rendered through Adobe Render Queue. Ive deleted every adobe product as well as the CC desktop app and reinstalled with 2017 software with the same issue. Anyone else with a similar issue?

I just did a test and am not seeing the same thing as you are. Can you try exporting a test from a new project and see if you get the same results?
