The list of solutions that they posted for this error included note of ESENT E916 in the event viewer.
I'd just like to inform that this "error" is irrelevant, it's a message that is logged when something writes to disk.
The game causes this entry to the event viewer by writing to a log file in ms2logs folder after disconnecting the player.
ESENT E916 is not a cause of Error 10053.
