New MIUI themes not working at all for me !

Jan 20, 2013
Hey guys, thanks for everything you've done for our phones, MIUI is the best thing that ever happened to Android !

although, i have a very annoying problem since i got my i9505,
with every week's release, i have the same problem, whenever i apply a theme, after a short period of time, the launcher FCs and it goes back to the original theme, i tried some free themes, and bought 2 premium ones, they all cause the same problem,

is there anything i can do ?
