Re: Error 624 fix help please`?
@Kittekassitar Are you seeing lag in-game, or just in the launcher? Issues with the launcher itself shouldn't be causing any in-game symptoms.
Anyway, for the launcher, try clearing the cache for Internet Explorer. Even if you never use it, the launcher does for some purposes. Be sure to uncheck the box to preserve data for favorite sites.

If the game is lagging, please run a dxdiag and attach it to a post.

Please also let me know what world(s) you're currently playing in, and whether you've taken steps to manually limit your in-game framerates.
