I am using Photoshop CC with Windows 7 64-bit and all plugins have issues detecting my internet connection. When trying to use them, an error message pops up saying "No internet connection detected." I am connected to the internet, am able to connect to Adobe servers, and am not using a firewall or connecting through a proxy server. I have checked my plugin settings in preferences to make sure plugins are allowed to use connections, and have tried editing the registry values in Windows to make sure that all Adobe products automatically connect to the internet, but still have had no luck. Plugins I am trying to use are Kuler and Subtle Patterns (a third party plugin). Any help/suggestions would be much appreciated.
Kuler is an extension, not a plug-in. A subtle yet significant difference in this case. Either way, I would suggest checking the Kuler forums. It seems there are a number of postings on this very issue:
