Hi. I am getting the same problem. I am running a 64 bit debian, and planeshift has worked for me two releases ago. (1.39 or something like that). 1.40 has not worked for me either, but that was due to some lib boost I can't install. Is the server down right now, or is it just me and demonrise cannot connect to it?
would I be more successful compiling source myself, or is this just a network issue?
The game does not tell me something is wrong when reading the terminal output, the only issues in that have to do with duplicate textures textures I think.
I also cannot run the updater.
and sorry to be of no help whatsoever, good luck fixing the chess problem (my guess is that at some point you told an application to run with chess, and that has become the default for unknown file types this has happened to me). Are you using windows or linux?
