Error when running step 10 of installation

[dandante]

Hello,

I installed nuPG on my M1 mac Mini running macOS 12.6 Monterey and SuperCollider 3.12.2.

During installation, I could not find a quark called 'JiTLib_Extensions' in the Quarks UI, but based on the documentation I installed it as follows:

"JITLibExtensions".include;

In step 10 of the installation, where I draw data into the pulsaret and envelope screens and then press > next to 1 on the TRAINS++PRESETS GUI, no sound is produced and the following appears in the post window:

ERROR: Message 'at' not understood.

Any idea how to fix this? Thanks

I am also having this exact same issue. Has anyone resolved this?
