Need help with migration of Sonar X3 project to Sonar Platinum

Hi! Just have some problems with correct migration of X3 projects to Platinum. I ugraded my PC from Windows 7 to Windows 8.1. All plugins installed, all proper VST too, and problems came from unexpected side. Both version had CA-2A compressor, installed as ProChannel instances on several buses. I also installed CA-2A to Platinum, but every time i load older X3 project, Platinum shows CA-2A as missed plugin on all my buses. May be i need to do something different? I cheked CA-2A - it is available as ProChannel and VST in Platinum, so this is strange that Platinum unable to recognize it in X3 project. On Windows 7 everything worked fine. But with 8.1 something changed. Any ideas?

I tried, the problem is that both X3 and Platinum see CA-2A as ProChannel plugin and VST plugin, and it used in X3 projects only as ProChannel plugin. But when you load X3 project this insatnces marked as broken. This happend affter migration to Windows 8.1. Project from X3 and worked on Platinum + Win 7 combo smooth. Well, may be something changed in folders this time? Because i installed Windows 8.1 from scratch, as well as all plugins.

Search and rescan did not help. CA-2A already installed, visible via ProChannel modules, or VST list. You can create new projects inside Platinum using it. All problem begin when you trying to open older X3 projects. In case of opening older projects, Platinum shows CA-2A as missed plugin. 

Sorry, i mean reset and rescan. Will try it ones more.
