1. "Warning 1: Unknown error.' - Doesn't allow you to access the guild, access your daily quest loots or get your story quest rewards
2. "Network error. Retry?" - Doesn't allow you play your daily or story quest or allow you into the game proper
3. "Warning 302: Data Error - Denies you of tourney rewards
4. "Warning 90000000001: Access error" - Corrupt file and denies you access into EW3 game
5. "Warning 2001: Data error" - denies you of your loots
6. "Level UP" - you level suddenly goes down by one step and then after about a game, goes back to your normal level
On a lighter mood, there are also intangible errors:
1. "Warning 419: Hackers Invasion" - when you are denied of a fair game
2. "Warning F9: Glu Error" - associated with a developer who is more interested in churning out games than solving problems associated with the games.
This is not how to be a developer, glu.
