That's about all you can do .... wait.  Marketplace has had some issues this week.  LL upgraded software last Tuesday and have been flushing bugs out of the system since.  Most people aren't having any trouble getting in, but you are not alone.  Meanwhile, go shopping in world.  There are great shops all over the grid.
