Then you should mainly be disappointed with Club/Standaard
but I think this won't stay an issue for long (because the Standaard version has been working quite well for me, and Standaard and Club are one company).
What you might try is, simply create an account on Standaard Boekhandel, and use that to log in to the webreader. (or if you already have an account on club, try to login to that one via the Standaard website)
