Hello chaps, we need to understand what the problems are.
We are aware of the issue with the username/password error which people are seeing but are there other errors as well ? We are not currently aware of any.
When you say it is not working which client is not working and what problems are you having?
All the clients use the same service and therefore it would be useful for example to try the Firefox client and, if you are a Window user, the .NET client as well.
That way we can see if the problem is on the service or client.
