ACR 'Checking Protocol Version' ?

I am having trouble connecting to ACR - was just playing the CArdsChat FR - placed in it - which is great... but...

After that game ACR seemed 'hung' so I exited and I just see 'Checking protocol version'.

Does anyone know what this means?

They must be in a constant state of Fix! I tried to open an account there to play in the super FR but could not get signed in or online and after a few days of trying, I deleted it all.
