i droped the item, pressed m for mark and typed egobind, but doesnt work. how should i do to bind the item? :S

to bind a item you must mark the item ( not sure but i think it has to be in your inventory ) type /egobind and then look at the chat screen that shows all the "/me" commands and "you begin to rest" stuff like that, it will display a message on it saying something liike "to egobind this item type /egobind 47823766" type what it says to type in the message, and the item is now egobound to you.

i open the inventory, i press M and the inventory closes :S

Keep SHIFT held to keep the inventory open.

thanks
