After installing the latest upgrade to PS Elements (13.1), the plug-in for Lightroom loads the previous version of the PSE Editor (13.0). If I load directly, I get the new 13.1 version. Applications folder shows the new 13.1 folders and the new version of the PSE Editor. I am using iMac 12 GB 2.8 GHz Intel i5 with OSX 10.9.5. I have rebooted to no effect. How do I rectify the situation since I can't change the external editor in Lightroom Preferences - LR chooses it automatically.
