[Solved] - Saved Song hangs Sonar when I load it

I have started working on a song and spent quite a bit of time on it so far.
I used three of my old Xpansion Tank 2.5.4 sample modules in the track which sound great but when I now try to reload the song X3 just sits there with the rotating circle cursor and never finishes loading.

All my other tracks load fine and even one that uses a single Xpansion tank module.
I plan to try Sampletank 3 64 bit using my existing sample modules now that it has been released but in the meantime I would at least like to be able to load the song so that I can remove the Xpansion plugins that seem to be causing the problems.
 
So is there any way to load the song and tell Sonar not to load the plugins?
 
Thanks
