The config file - there are new lines there, but I guess since you're looking on Windows, it doesn't recognize them. But the program does see the newlines there, so that should be ok.
What do you mean the PIREP was there, but no data?
Always update all of the files, sometimes I do multiple updates in a day (like yesterday or the day before there were 3 commits), so you'd have to update every file listed for each commit from the last update you did. That's why it's just easier to update it all.
