[Unity 4.6 GUI] UI Buttons have stopped working on Web Player

Hi Unity Community !

I have the beta version 4.6.0b17 of Unity (the demo version, not the professional) and my GUI buttons doesn’t work anymore in the Web Player (Unity Plugin version: 4.6.0b17). It’s fine in Unity, even in the windows executable build, but not on the Web Player (and it was working few days ago).

I am the only one to have this issue, any known bug for the Web Player ?

See here the issue

Thanks !

Even my last project stop working by his own (project with the new GUI from the 4.6 too). I have made some screenshots of what the menu looks like in Unity editor/Windows build and in the Web Player (with error shown) :

Real version :

Web Player bugged version :

Errors I have : TypeLoadException: Could not load type ‘UnityEngine.RenamedSerializedDataAttribute’ from assembly ‘UnityEngineUI’.

It seems that I’m the only one to have that issues, I just don’t know what to do and the issue is not only from my browser/computer. All browsers have the same bug and other computers too.

Someone can help ?
