Error 7

Err no 7 is an error message that is displayed by the game at times. It comes after the player has been disconnected from the game. It is unknown what the specific reasons for this error are. As seen in the image, it seems to be a network error but not much is known beyond that.

Err no. 7 is lethal and there is no way to recover from it and rejoin a party. Often when a player has been disconnected and reconnects, they will privately message one of their former party members with the message: "Sorry, errno7"

Note: Some players may simply be using that as an excuse.

To help combat Err no. 7, players can file bug reports at Guild Wars' support site and let them know of the circumstances of the error (which area, what time, ..., etc).
