I only get [Method error 12031] in return an all of them. I hade the same problem when implementing them the first time but I then found the answer in thread 1393072 and referenced threads. This time however I am not able to find anything that helps me. I have tried to migrate my July CTP projekt to a new empty 1.0 Beta project but it doesn't help. Have anyone else hade the same problem? I am grateful for any suggestions and tips!!

That's been bugging me all morning. Although I didn't have [Method Error 12031], I had [Method Error 500], this solution still worked for me.
