I have seen them post here in Problems and Support occasionally on weekends, but I don’t know whether they have official weekend hours or have really overzealous staff who just can’t wait til Monday to help people.
One thing to know for future issues is that posting in P&S opens a new support ticket, and having multiples can slow things down as they have to search and try to match things up, so it’s usually best to pick one method and stick with it. The advantage of posting here rather than using email is that there are a lot of helpful folks on the forum, and sometimes we can help you find the problem before the staff work their way down to your ticket. (And we “work” on weekends!) So, since you’re here anyway, you could tell us what’s going on and what you’ve already tried, and worst case, you’ll have sympathetic ears to help you get through the waiting!
