Sorry isn't quite enough

I pay EUR 12 for about as many hours of internet access (less the time I spend sleeping, you do the math), and then when I try to actually use it, after having been out to De Balie for a few hours, I get this message:

Sorry. You cannot be logged in at this time. Please try again later.

The login page also says:

swisscom eurospot – it’s secure, it’s reliable, it’s swiss.

I think not. And the clock is ticking. Argh!
