I am trying to run PS on Mandriva 2008 and I am having the same problem as this person : http://hydlaa.com/smf/index.php?topic=32731.0   ( client failing to launch) but I am not very tech savvy to begin with,  I am brand new to Linux, and  when he says "I ended the session and logged back in then it worked"  I am really not sure what he is referring to.  Following the links posted on that page don't help me much either.  None seem specific to my problem and most are too technical for me to understand what they mean or where I am supposed to input the code.  Nobody in the Linux forums has been able to offer me advice.  If someone could explain to me in simple, Sesame Street terms what I need to do to make to program launch, I would be very grateful.     I also have the same problem when I try to run the updater.
