Installing PiCorePlayer & Squeebox

I'm trying to install PiCorePlayer and Squeezebox, following the official PCP tutorial.

Things seemed to run fine until it got to the Install LMS stage, where it's supposed to refresh the web page again to go on. But it did not.

On the Raspberry screen, the last line says "SMP: failed to sotp secondary CPUs". It seems something went wrong, am I right?

What can or should I do? Start installation all over again from the beginning?

Thanks!
