Ok. so my problem is when I join a mutilplayer server or start a single player one every block is invisible except mobs water lava or signs and maps on walls. this started after I tried to install the backpack mod for 1.5.4 ;o and then I deleted the jar and the verison so it should have fixed it I even tryied a hd texture pack didn't work I even reinstalled it didn't work any suggestions?
As for your question, if you haven't deleted your .minecraft folder and re-dowload it, then do so. If that doesn't work, update Java.
So I deleted .minecraft and the shortcuts I reinstalled java and reinstalled mc and still the same but before this happened I had the fatal error glitch so when I start mc it shows that but then says starting launcher and works as normal this started after trying to install the backpack mod I need help please Q,Q but I noticed that when I go to resource packs and hit done it shows the textures for 2minutes and but also when I join it shows for 4 seconds help q.q
