Horizon not working

I downloaded the latest version of Horizon and it keeps asking me to download the update, i have downloaded the update, yet it still tells me that the data is corrupted and that i should obtain a new copy, i download the update again and still get the same result. HELP, this is therefore making my diamond membership useless to me…
