Re-saved version, works with Opus 10 or above:
Nudel Sand.dlt (1.99 MB)

Original version, works with Opus 10 or below: (2 MB)

I am using Directory Opus 11.25 (x64) and have an error trying to import this theme into Directory Opus.
I am using this theme for many years thru all versions of Directory Opus.
Is this an error?
Can someone fix the error?

I've re-saved the old theme so it will work in Opus 11 again.
