So my start screen is not showing up anymore , I have tried deleting the "startscreencache" folder and restarting but nothing happens.
 
So i have Sonar professional and platinum installed , Had Pro first and then upgraded without removing the Pro version.
 
I have been meaning to do a complete refresh install of just Platinum for a while now and this is as good a time as any to do it ,Thing is i have two of everything showing up in command center .
 
What is best way to completely remove all Sonar from my Pc and then just install the Platinum edition  ?
 
Also will all my extra`s be fine , Like Melodyne 2 essential and Addictive drums  ?
 
 Edit - Its not even doing the initial scan for new plugins or anything now , And melodyne 2 shows up in CCC instead of Version 4 
 
Edit 2 - Rolled back to previous version and then did update again - All working flawlessly again !

Both the start screen and scan are controlled by preference settings.
Logging out and back in the Command Center might clean up the dual listings.
Clean reinstall instructions for SONAR are https://www.cakewalk.com/Support/Knowledge-Base/2007013392/SONAR-2015-Clean-Install-Instructions or for everything Cakewalk https://www.cakewalk.com/Support/Knowledge-Base/2007013372/Clean-Install-All-Cakewalk-Software. Neither will affect AD2 or Melodyne.
