Warriorstrike does have a point, sometimes your computer cannot handle as much so it crashes. The same thing that happened to me in Fluorite plains, I was loading two characters and the game started crashing because there were too many users and movie makers.
All I can tell you is try to close some tabs or programs in your computer and stay at another map for the mean time, then it should work. Your memory is being taken up by programs that are opened. If you try Paintool SAI for example, it shows you how full your memory is every second below your screen. I once opened Feralheart, skype and 5 tabs in google chrome, then Paintool SAI crashed (and I lost my work, which got so annoying).
