When I launch the game it usually launches right, but then when I try to go into a world (new or old=same results) either it doesn't load at all and just crashes or it loads the world (barely) but I cant move the cursor/view and all that can be seen is blue of a still loading/generating world. And then it crashes.
I have attempted to fix this error myself-thinking that it was a problem with my PC but I don't think it is-by uninstalling the game and then reinstalling it. I have even completely scrapped my PC and then tried to install Minecraft. But the results were always the same(the error described above)
I DONT KNOW IF THIS IS A SYSTEM ERROR OR IS JUST WITH MY ACCOUNT SO I WILL JUST LIST WHAT I DO TO TRIGGER IT.
1. Open Minecraft launcher
2. Launch Minecraft (either version and get same results)
3. Play "Singleplayer"
IF GAME HAD NOT CRASHED YET THEN...
4. Select world
5. Wait for world to load
6. The world almost loads (blue, cursor, beginings of a quick bar, cant move cursor)
7. Wait for the crash because that is as far as it ever gets for me.

I would send the code error but the new version does not have that.
Should I send you my login info so you can see the problem (if it is not server wide)
