EAC sandbox not active

This is what works for me, first you must have hdd.

1. Copy the apex file from origin games folder to the hdd

2. Uninstall apex and origin

3. Reinstall origin, and also install the apex once again

4. While downloading for about 50mb pause it and close the origin

5. Find the new apex file on origin games folder and delete it. 

6. Move the old apex file from your hdd to the origin games folder

7. Open origin and resume the download.

8. You all set
