I've followed every step from this site: http://modthesims.info/wiki.php?tit...s/Not%20Working
but it's still not working. I really don't know why!

I have Windows 8 and 64bit

GameVersion = 1.0.631.00002
Code:0.DL-0.0.11195
Asset:1.Content.Devtest.1397
Thumbnails:1.Thumbnail.dl.933
TCC:1.TCC.dl.1209
CiderVersion#002432

Resource.cfg:

I hope you know if I've done something wrong because I really don't know what to do, that this is working!

concerning your game version:
is your game patched? if not patch your game. Game Help: TS3 Patching

a similar problem was reported in the following thread and a certain patch level is needed (see Hysterical Paroxysms reply)
