Hi , I have a problem with minecraft 1 month ago I played MC and it worked really well I think version 1.2.5. Now I missed playing minecraft with my friends and when I started it and updated Mojang Logo toke like 15 sec to disapear usually only 5 and instead of appearing like normal it appears like scrolling down. But when I get to the Menu It just Stops Freezes, in the Menu if i click on something it says (NOT RESPONDING) before it worked all fine and my pc didnt even got slow when freezed cuz i could open other things fast althought this was using 99% of my cpu.

Pls i need help i miss playing MC
And my PC meets the requirements.
