The problem started when my Minecraft was updated from v1.4.7 to v1.5.1, since I was using mods, I had to search for the new version. I just use 4 compatible mods (ModLoader,Optifine,Rei's Minimap & TreeCapitator) for v1.5 and 1 tecture pack (Soartex Fanver). When I was using the v1.4.7, everything was working perfectly, now it seems that the ModLoader is the problem (I already checked it).

My ModLoader version is Risugami's last version for 1.5 (it has 28 files) and the other one I was using when I had v1.4.7 had 30 files.
