There is a problem with all versions of this for IOS. I'm not sure if it will let you through if you download level 9 before you complete the level 8 trophy hunts, but most of us did this a long time ago so no way to check. Hopefully the developers notice and sort it.
Yes, this seems to be an error with the new release. No one with IOS phones or pads can access the new DH 2014 level 9. Hopefully the developers notice these comments and sort it sometime soon.
