I purchased the ERSX and P&B content packs a while back - while they've been working up till now, yesterday the BW9 switchers from them have decided to stop working, with the error that they can't find the Alias Mesh in the EOT library. I've cracked open the library and the meshes are decidedly there. Plus, after re-installing the content packs, commiting them just makes them vanish. Please explain how to fix it not recognizing the right mesh is in the JR EOT library.
