Since Flash (the platform Graal has been running to play iOS servers on PC) is going out of commission soon, Graal came out with a new WebGL client (which is radically different from the Flash platform) to play Era on, which is what the new update was.

It's still in its early phases, with quite a few bugs and issues, but hopefully those will be ironed out fairly soon.

Unfortunately, there isn't a whole lot you can do about it until all those issues are fixed.
