Plug Manager Bundle

Does anyone know what the Plug Manager Bundle is? (on Mac)

I am finding that if I try and open either Cubase 6.5 or Nuendo 6 in 64 bit mode, the programs crash when trying to load the Plug Manager Bundle. This comes near the beginning of the start up process, after loading GUI Resources.

Disabling plugins has no effect. Where should I look to solve this one? :unamused:

any help most gratefully received!

PROBLEM SOLVED:

I uninstalled the recent update to East West PLAY 4, and reverted to their PLAY 3 version. Cubase 6 now loads up without crashing.
