Unable to create a sandbox account

[elmak]

Hi, I'm trying to create a sandbox account but it's not working. I get an error: “registration failed”. What should I do? I need the account urgently

I had the same problem but I just found a workaround : it works if you only fill the required fields (leave the address empty)
