Nova Skin update problem

With the new Nova skin update the texture packs no longer work with my minecraft 1.6.4. Why?

You’re client is too out dated for the texture pack…i think thats what happened when i played 1.8 with my 1.7.9 texture pack the steve was upside down

Attackontitan, it is possible. But even the old versions of the site do not work for me. To put it simply: I will download the zip file, put it in the folder, open minecraft and click on the resource pack. But when I load up the world the resource pack I am using makes no changes.

oh well i thought i might help xp
