I have CS6 & OS X, v 10.6.8, snow leopard. Tryiing to use photomerge I get error msg #19 with a long list. Any ideas? After calling Adobe, I was advised to uninstall my NIK plug-in & reinstall CS6. NIK says that their software has no effect on CS6 Photomerge not working. Have not uninstalled CS6. Should I try this? Help. Thanks in advance.
