Can't get C of C or into game

When I launch C of C, it says "Good news, an update is available", so I click on "update" and it takes me Game Center where I click on "open". I am immediately taken back to the C of C screen that says "Good news, an update is available".

i have tried to update off and on for a day. I have rebooted my iPad---all to no avail. In the mean time, I get nice messages saying that my village has been raided.

I know others have updated without problems. Any suggestions would be appreciated.

I have had the same problem as Sunshinebloke for two days now without a resolution. Within the past few minutes, however, I received notification of a new iOS (10.3.2). I downloaded it, when back to CoC and all of sudden the Game Center screen now showed "install" instead of just "open". I installed the update and all is good.
