I know a number of people have encountered this problem. But the answers I have seen don't help. I am trying to import the latest openLCA methods database into openLCA. It is listed in nexus as a json file and downloads as a zipped file. Unzipping it just creates a folder with subfolders containing a number of file types. But the import function seems to only want .zolca files. Very frustrating. What am I doing wrong???? URGENT.
