Open beta for Warhammer Online: Age of Reckoning kicked off this past Sunday, September 7. 

However, its European launch hit a few snags, and GOA, the game's publisher and operator, has issued a formal apology to hopeful gamers who were unable to log on with their registration codes.

Ghislaine Le Rhun, GOA's chief executive, made a post on the European WAR site early this morning:

Dear all,

I rarely address players directly, but I wanted to write you as too few of you have been able to access the open beta today.

As my team explained in the previous post, although we have opened the servers and corrected numerous issues during the last 24 hours but we have not yet solved the issue of saturated Open Beta key activations that we’re currently experiencing. I am sincerely sorry for this, and I understand all the frustration the situation has spawned.

Today was a dark day. We expected a massive influx of players, but reality was even harsher.
I personally commit that we will communicate to you as clearly as possible on the resolution of these current issues. My goal is to give Warhammer Online the success it deserves. Be ensured that all GOA teams, with Mythic’s support, are working hard to bring you the best possible game experience.

Best regards,
Ghislaine Le Rhun
GOA CEO

An earlier update to the site confirmed "serious problems" with the authentication system on top of exceptionally high amounts of traffic and an unidentified problem that slipped through the cracks during playtesting.  As a result, only closed beta testers and a lucky few new players were able to get in without any complications.

The WAR team has been working around the clock to resolve these issues, and they're expecting the game to be 100% back on track by late Monday morning.
