WoW 3.3.5a Large Aware Adress Issue

Hey guys, I deleted my old client unintentionally (modded and flawless client, no crashses or glitches whatsoever) and this time I can't manage to get LAA working... I open the software several times, forced LAA, it won't save the settings, only the "Set original to True"!! The LAA flag is always False everytime I open... Did I miss someting? Or ir just something with my client/Windows? And I know this is the solution to my Dalaran crashes due to "Not enough memory"

Any advice is appreciated
Kind regards

Nevermind guys, I managed to solve the issue myself, using CFF!! Thanks anyway for the time waisted!
