Updating firmware on Line 6 DL4 MkII

Anyone update their DL4 MkII recently? I’m trying to ensure mine has the latest firmware, but my Mac won’t open the most recent Line 6 Updater 1.28 (the one for Mac systems) because it says it itself needs to be updated? Unsure what to do. I can drop them a line on the support page if need be but figured I’m not the only one to have run into this. Thanks in advance.
