I know they did. Didn't mean to make it more confusing, so I just switched everything back to as basic as I could make it. I'm just clicking file, selecting new station, adding a name for the station in the already selected WEATHERLINK folder. No matter what name I add, I get directory already exists. I dumped the weatherlink program, emptied the trash, downloaded it again, same outcome.
I see what you're saying about the error codes not being accurate, I can only find one other person who reported this, and it sounds like they had an update issue. Mine is a new install of 6.0.5 from Davis. Haven't had weatherlink on this machine previous to trying this setup.
