Full of Life Texture Pack stopped working on Realms

Hi,

about two months ago I bought the Texture Pack called "Full of Life".
I used it on my Realm without any Problems at all!
Yesterday I stopped playing so I hit "Save & Exit" and closed Minecraft like normal.
Today I reopened the Game and somehow the Texture Pack stopped working!
I didnt change any Settings on my Realm at all so I dont know whats wrong with it.
I tried to deactive and reactivate the Texture Pack but its still Standard Texture Pack on my Realm, no matter what I do!
I also noticed that the Texture Pack is still activated but just wont Show on my realm anymore!
