What is causing this? It just happens when clicking on totally random, mod AND vanilla items in my inventory.

The server keeps disconnecting everyone and now I can't reach it at all. What's wrong with it?

I installed all the mods but it won't recognise the backpack mod! It's the right version, it's in the mods folder, but when I try to connect it tells me I still need to install it. What's wrong?

So I just got a Macbook and downloaded Minecraft. It said I needed to update Java before I ran it, so I did. I tried running it again, I logged in, it downloaded the packages, but then a black screen. After a minute or two it came up with this error message:

I have no idea what any of it means and I have no idea what's wrong. The Mac definitely meets more than the recommended requirements of Minecraft, and yes, I download the Mac version, not Windows. So why won't it run?

So here's my dilemma. I'm getting Windows 8 tomorrow and plan to completely erase my laptop hard drive that's loaded with viruses and corrupt system files and replace it with W8. But of course I'm a big fan of Minecraft and don't want to have to stop playing the PC version since apparently tons of people are having issues with Intel HD Graphics and the "Bad video card" error or whatever. Right now my laptop is too slow to run Minecraft without terrible lag (even with Optifine, and it used to run it great) so I am definitely upgrading when I get W8. My other computer is fast but has pretty much the lowest graphics that exists since it originally used WXP and was meant for documents, not games or not even media. It can't run Minecraft no matter what OS it has on it. And I can't afford upgrading it at all for quite a long time. But back to the graphics...I've tried the demo of W8 (after its release date) on my laptop and of course I get that bad video card with opengl error or whatever so I went to try to download a driver that works for it. There wasn't one. I would love to reinstall W7 but there's no way I can afford to buy another W7 Ultimate x64 disc right now or anywhere in the near future. Do I have any options if I want to keep Minecraft working?

Quote from minecrafterwork

Your error seems to be occurring in your map, if you can try resetting your map

I have tried deleting the world folder and the saves in the .minecraft folder but it still happens.

This is probably my favourite mod. Like. Ever. I just have one little problem. I tried the mod out in creative mode and went and caught myself a few Pokémon and I couldn't wait to try it out for real in survival. So I deleted the world and started it back up again. But in the new world, I started off with the Pokémon from the world I just deleted. I completely reinstalled Minecraft and added a fresh installation of Pixelmon, but somehow the same three pokemon were there in my party when I started up the mod. I can't get rid of them without releasing them via PC. That's not supposed to happen, is it?

So earlier I was able to work my private server just fine, but I decided that the mods I wanted to use were for 1.4.5 not 1.4.6 so I used my backup of 1.45 and but the server said it was still loading 1.4.6. So I went and downloaded the server for 1.4.5 and this is the error I get when trying to start the server. The IP address is correct, and the only mods are Forge with Pixelmon and OptiFine (I get the same error without mods). So what's the problem?
