My PS client returns a "The Server Isn't Available!" message when I try to connect.  It worked yesterday and I didn't change any settings; I checked to make sure that the server was up and it is;  yet even the updater's ping won't detect the server.  What should I do?  I've already tried disabling firewalls and restarting, still no luck.

I have a similar problem, receiving the \"Warning: could not load plugin \'crystalspace.sndsys.manager\'\" message, but for me there are a few different problems:  The login page shows only white background and the shadows of the text;  the character creation page only shows text shadow and actual redered objects (hence, text without shadows doesn\'t show up); and in-game, the textures for the buildings and most everything but specifically rendered objects (i.e. crates, carts, player model) shows up as a black background.
I\'ve downloaded all the updates that the update finder could find, yet it still has this problem.  I\'ve also tried a different skin, and it didn\'t help.
