I touched on this in a previous thread[1], but superconductors only stay superconducting below not just a critical temperature, but also below a critical current density and critical magnetic field strength.
These limits are different for different superconductors. It could very well be this superconductor has really high critical temperature but really low critical current density, in which case you can't have lots of current at zero resistance.
