I never got a crash saying anything about “free trial is over” but I too can’t see any guild members, only myself and friends show as offline when they aren’t. I also can’t see all party members but as you say it can be fixed by logging out and back in (annoying!) I also can’t take crafting material & certain things out of my bank or guild bank. It just wont work. I’m tired of not being able to see or type in guild chat also. I hope this gets fixed soon!
