Installed and reorganized KU11.  Was able to open Kontakt 5 stand alone and set new options and database parameters fine.  But now K5 will not open at all and keeps giving "the instruction at 0x---referenced at 0x--- the memory could not be read error dialogs (sometimes its the memory could not be written).  Also, since K5 is part of my "normal" template that SPLAT loads up on startup Sonar won't load either...unless K5 is uninstalled.  I've tried uninstalling/reinstalling K5 and restarting/rebooting several times to no avail.  Any suggestions????
 

Check for an errant Kontakt dll in a location you don't expect. If you find one, rename it (Kontakt.dll.old) so it doesn't look like a plugin anymore. Sounds like you are loading an older version of the plugin...
