I'm unable to import any ULD files from ERCO in DIALux 11.1. I'm downloading the files from the ERCO website. DIALux displays the following message "Luminaire data could not be imported."

Below is the download link for A5000160.

Is anyone else experiencing this error?

I'm unsure if this is a new bug from 11.1 or if their files are not supported.

Update: I've installed the ERCO plugin from their website, and I'm now able to add the Luminaires.
