Try uninstall FlashEff Nano first then follow my instructions.
1. Open Flash CS and go to Help/Manage Extensions menu 2. Once the Extension Manager opens, press the Install button and choose the FlashEff's mxp file. It's essential to launch the Extension Manager from Flash CS directly. 3. Start an AS3.0 project. The component should be there. If not, restart Flash CS. See the video tutorial for installing the component here [www.flasheff.com] If this doesn't work, please let me know.
