Livery manager and win XP X64

I use Windows XP 64..and cannot get the livery manager to come alive..when pressing the select a livery button, Now I know with Windows 7 ..you right click...and run as administrator...but this does not work in XP 64, If you use XP64 ...and have made this work....would you explain the steps you used, I put the question in a support ticket...But I know they are very busy..and may not get to this small itemand I would not blame them... as I know they have not been getting any sleep lately, Thanks and Best RegardsDon Nelson
