After Effects can't connect with Adobe Media Encoder. Always says "AEGP Plugin AEDynamicLinkServer: Adobe Media Encoder is not installed. Please download and install it to use this feature 5027::12" when I select Add to Adobe Render Queue
Though I have Media Encoder, this happens.
Nobody can tell you anything without proper system info or other technical details such as the exact version of AE.
