I bought tickets to Robbie Williams on Ticnet last week, and noticed some differences in how this was handled. 15 minutes before the tickets are released everyone is logged out, so far normal handling. After some minutes the login is reopened, BUT you will automatically be placed in a queue. Then all you can do is wait... I wasn´t aware of this new handling and was a bit late in my login, but still got my tickets half an hour after the tickets was released.
