pomoc prosim

cau lidi prosim co mam udelat kdyz me to po prihlaseni ihned odpoji nebo mi to napise toto :

Out of memory !

Minecraft has run out of memory.
This could be caused by a bug in the game or by the
Java Virtual Machine not being allocated enough
memory. If you are playing in a web brouser , try
downloading the game and playing it offline.
To prevent level corruption, the current game has qut.
Please restart the game.
