Deleting older version of Sonar

I have X2, X3 and now Sonar Platinum all installed on my computer.  I completely loved sonar X3 until I started using UA plug ins and now its unusable.  So I bought platinum thinking the problems would be fixed, some were some were not.  It crashes a lot now.  Every time I open a UA plug in, the sound engine stops and it routinely crashes 5-6 times per session.  Prior to UA I almost never crashed.
 
I never use the old versions of Sonar, so I thought maybe having less "stuff" on my PC would clean things up a bit, maybe even thought that would help, but I am afraid to uninstall them for fear I'll make things worse.  If you have an upgrade version of Sonar and you uninstall the older versions does it do anything bad to the newest version?

Maybe it's time to troubleshoot your system. Having multiple Sonar versions on your computer won't be what's causing problems with UAD. As far as I know the latest UAD version work perfectly well with Sonar Dorchester.
