Zombie saves were acually patched bro. It would say "Your save is not compatible to this version of the game" or somewere along the lines there.
But thanks to FiLTH he found this dvar something like savegame_Available "1" not exacly sure if thats it but with that dvar it allows you to be able to save in solo zombies then you get the new version of the save. Before the old one got patched it was hotfixed so you had to be disconnected from live to beable to use a zombie save.
