I have a DS-7816N-E2 that was originally running multi-language software. Long story short, the software was updated to the Chinese version 3.3.9 and remained multi-language. I was having an issue where only one camera would show up in iVMS so I reset to default via the menu in an attempt to resolve the issue. Unfortunately, it has now reverted to Chinese. Any idea which software I can put on this to get it back to English? Thanks.
