my guess is the prf includes objects from a .lcf, which are not compatible with the .libpack.
the move to .libpack is understandable from a software development perspective, but it's been disasterous from a template management and file migration perspective

From which Archicad version is this coming? The prf files are a bit brittle in my experience. And while sometimes the error dialogs are crude, here the culprit is already stated plainly and easily understandable.

If you still have the file from which you exported these I'd rather take the file itself (instead of loading a prf or xml you can load favorites from .pln project files directly. When the version numbers are different that is the recommended way (and only wroking way...?...) by GS anyway).

Personally the prf have bitten me before as well so I would not use them anymore, instead only rely on XML.

But again, that's mostly made for exchange between the same version.

By the way: This has been asked numerous times before in the forum – you'll find plenty of answers if you bother to search for it.
