SOLVED - Bit again by uninstalling earlier SONARs - plug-ins lost

I guess I just don't learn. I just bought X1 and the README said to uninstall previous versions before installing X1 because that way I wouldn't lose my plugins.  WRONG !  I had SONAR 3 and SONAR 6 installed and copies of all plugins are saved off on another drive... just in case.

So after I uninstalled 3 and 6, I went into SONAR 8.5 Producer (x64) to load a project and guess what?  All my plugins are once again lost *they were all there before I uninstalled).  So I figure, OK, I'll just go into Options > Global > VstPLugins dialog and reload them.  NOPE !  Even though I have 4 folders listed with my plugins, the "Scan" buttons are disabled and I cannot seem to get them enabled.  Can someone help me get my plugins back please?  I don't want to have to dig out my old CDs and reinstall them.  I have the plugs saved off and would like to be able to copy them back into the production SONAR folder and have SONAR find them.  Thanks.

PS - I also went into Cakewalk Plug-in Manager x64 and tried reloading the plugins there and same thing - Scan button is disabled.  Sigh

Oh happy day !!  I installed X1 and it scanned all my plugin folders and all my plugs are restored by X1 !!  WOO HOO !!  I love you, Cakewalk !!  And when the X1 interface popped up for the 1st time... I LOVE IT !!!
