Yes I'm having problems too.
I eagerly downloaded because I'm a LASS user, but now upon loading my existing project the 32-bit server crashes. Also, all instances of VEP receive midi at the same time. In other words, even if I'm playing on a non-VEP track (say B4 or Trilogy), the VEP instance(s) play regardless of the channel setting. It of course doesn't work the other way - playing a VEP instance doesn't trigger a non-VEP track.
The midi 'all receive' problem, and the 32-bit server crashing occurs not just on my existing project, but any new project created since the update.
With regret I'm going to have to go back to the previous build.
