Custom Nodes not loading (incorrect format)

Hello,
I’ve been using Dynamo with Advance Steel and it always worked well. I’ve updated it today (it was 7 months out of date) and I had some issues with the new version.

Everytime I save any modification inside a Custom Node (or create a new Custom Node) and then close Dynamo, when I reopen it, the Custom Node is not loaded (“Error: Custom Node definition is not loaded!”). The error message in the console is shown in the first attached image. However, these .dyf files are at the same folder as the ones that are still working (C:\Users\xxxxxxxx\AppData\Roaming\Dynamo\Dynamo Advance Steel\2.0\definitions).

I’ve realized that, after the update, Custom Nodes (.dyf files) are being saved in a Json format and the older Custom Nodes were all in xml format. It seems that Dynamo is trying to read them in a xml format, but it’s saving them in a Json format.

Any ideas about how to fix it?
Thank you!
