I use mac, and after I updated to the 0.5.5 version, and now I tried to run PS via the psclient icon. This time, the icon was missing, an empty icon instead of the usual psclient icon. I clcked on it, and it sayes it crashed. I tried it 10 times, and it just says the same message. I tried to run PS via the pslaunch, too, but it just restarts pslaunch.
