Uninstall all the Aeria Game & Entertainment games in your computer (since you don't play anything beside EE, there's no problem).
Delete the Aeria Games' folder located in your drive C:/.
Run a cleaning software in your computer to clean all the fragmented and corrupted files, I strongly suggest CCleaner
. (This step is optional)
Re-download and re-install Eden Eternal game from the official website, here
. In this step, the Aeria Ignite might get installed as well, but don't stress about it.
After finishing the installation, run Aeria Ignite and click in the Eden Eternal tab and then click the "Play" button.
If these steps helped you and you got it working, have fun!
Kudus to Law_Breaker for being helpful as well!
