I've been having a problem with my Minecraft. I basically not see blocks or mobs, however I can see entities on the ground (saplings etc). I have reinstalled my .minecraft folder at least twice, dedicated more RAM, reinstalled Minecraft around three times, updated my Java, updated my graphical drivers and still; it doesn't work.

I've tried going on Tekkit and FTB, made multiple worlds and joined online servers and it always looks the same... I cannot see any blocks.

Although, when I launched using FTb, the console displayed this:
2014-02-12 18:49:38 [WARNING] [Minecraft-Client] TextureManager.createTexture called for file textures/blocks/.png, but that file does not exist. Ignoring.

Any help would be appreciated
