This has happened so often I've had enough.
When I try to access the game it often states: 'invalid client: exit and update using the patcher'.
When I open the launcher it takes some 20 minutes to show any text (if at all) and then seldom shows the 'play' or 'update' button. If it does it often updates to 150%
The 'initializing' ribbon does not show any coloured bar more often than not.
(Strangely, I did manage to install update 5...since then nought.)
Often with no text I cannot 'repair' or fix it.
Therefore, I cannot access the game.
This has happened before and support could not come up with any meaningful work around. Shame, I think I will have to quit as it appears this launcher is broken.
Anyone else having these problems?
