I am having a strange problem. when i close the after fx project in order to open another, the dynamic link in premiere pro referring to that project in ae, then breaks. basically I have to keep the ae project open in order for the dynamic link to work in prem. I have never had this problem before until now. rather strange. if i create a fresh AE project and dynamically link that project. and close it down. the link does not break. some of my ae projects appear to have become "corrupted" I have tried SAVE AS and saving the AE project as a new project but the problem just carries across.
On a guess: Are the linked projects actually used on a timeline in PPro? If not, I could imagine premiere simply "forgetting" them on some occasions. Also, generally speaking, make sure you are actually saving the AE projects in the same root folder as the Premiere projects. DL may simply lose sight of the files because they are outside this folder hierarchy.
