Passive skill tree error?

Hello, I cannot access the Passive Skill Tree on this website. When I click on it, a black screen shows up. Any idea why?

Make sure java is up to date.
Close all browser windows, clear browser cache, try again.

Stuff like that.

It requires an up to date browser that supports html5 canvas. For IE that means at least ie9.

I'm looking into why there is no error message for older browsers.

I'm using the current version of Google Chrome. I will try updating my Java and see if that helps.

EDIT: I just checked my Java, I have the current version. (version 6 update 31).
I also cleared my internet cache and all that stuff.

Any other ideas?

it doesn't require java.

Do you use the extension ScriptNo or something like that?
An extension which would prevent javascript from loading?

No, I don't use that extension.

Last week it was working fine. Since ~saturday, however, all I get is a black screen.

No, I haven't changed anything with my browser.

The only difference I've made to my computer between last friday and now is that I downloaded and installed Path of Exile for the free weekend.

Obviously something changed. But I have no idea what.

and CTRL+F5 didn't fix anything?

No. :(

I might try reinstalling Chrome.

edit: I reinstalled Chrome, I still get a black screen. I then tried using Internet Explorer, and it works fine. So obviously its something with Chrome..
