Guild Wars 2 sold a million copies before the game's launch on Aug. 28, but ArenaNet seems to be struggling to fix numerous issues in the game. The developer announced on Aug. 30 that it is temporarily disabling digital sales of the game in order to expedite fixing the launch issues.

ArenaNet announced in a statement that it wants to ensure the "best possible play experience for our fans" as it feels the "high player concurrency may compromise player experiences. We have now reached that point."

Physical and digital sales are still available via retail stores, ArenaNet confirmed.

The developer took to Reddit to explain the issues with the game; there are ten key issues: account security, e-mail authentication, parties/guilds, worlds, overflow worlds, trading post, mail, botting, forums, and the next software update.

Starting at account security ArenaNet revealed it is seeing an increase in reports of account security theft.

"We believe hackers are using databases of email addresses and passwords stolen from other games and web sites, and pre-empting existing trojan horses, to search for matching Guild Wars 2 accounts which they attempt to compromise," it claimed. The "reset password" feature is temporarily disabled, and the developer is working on e-mail authentication. It advises players to use a unique, one-off password for Guild Wars 2.

ArenaNet is rolling out e-mail authentication, which will be compulsory for Guild Wars 2 players. With e-mail authentication, hackers will need to know the e-mail address and password of accounts in order to succeed. 

Other issues center on parties and guilds. Guild invites work only sporadically, while party members on overflow servers do not stay on the same overflow server and may not show on the map. On overflow servers specifically, players should be able to set up a party and then right-click on a friend's picture to select "Join" and jump to the overflow server.  

Worlds are filling up, particularly for German and French players, so ArenaNet is adding two German servers and one French server.

In response to abuse of the system, ArenaNet is making the Trading Post available to only 15 percent of players to help get the service back online. ArenaNet also saw abuse in the mail system, so the feature is temporarily disabled.

Players using bots are currently getting only 72-hour bans, though ArenaNet confirmed that it will return to its normal policy of permanent bans.

Meanwhile, game forums will not open until the "mass influx" of players decreases, so as to not put additional demand on ArenaNet's infrastructure.

Last night's software update aimed to fix many of the issues, introducing additional servers for German and French players and providing e-mail authentication.
