Not many runtimes there and I'm guessing they are on the same drive as your P7Pro? I was having issue with Vue not finding everything. I have all my runtimes except main P7/P7pro on a different drive. It all works in Vue from My P7 but I never updated it with SR3. Vue has a bad time with P7Pro.

So far my tests with SR1 have worked. Will try the Pz3's that didn't tomorrow when I have time. I'll try them again first I'll reload them into P7Pro and resave them out and see what works and what the differences are.
