I'm trying to get Part 54568 into Studio. I tried downloading the file from this link https://www.ldraw.org/cgi-bin/ptdetail.c.../54568.dat. However when I try to import the file into Parts Designer it says "Parts not found: s/54568s01.dat". I noticed I didn't have a subfile or something downloaded so I made sure to download the subfile from the link as well and its file name is 54568s01.dat. But even though I have both files downloaded, Parts Designer still shows the same error message about the missing part and I don't know what to do.
