I have Signastation 9 installed since 2006 on WinXP Pro SP3, and maybe have been 4-5 times reinstall it. Few month ago, sometime Signastation cannot run, after I check, it's happen because pbs.exe not processed in Windows Task Manager (in the installer guide tell: nmserver.exe, windowserver.exe, machd.exe and pbs.exe must running before Signastation executed, they are components of Apple Yellow Box Web Object). The original dongle always detected on PC and running well.
Maybe you ever find similar problem? How to solve it?
