This is not the first time I've had this issue, and certainly won't be the last I'm sure. I simply created a project, completed it, but some files weren't showing up properly. So I rendered, saved it, then tried to re-open it, and it gave me this annoying bs message AGAIN. I tried to run CC as administrator, no go. The project worked PERFECTLY fine before, but when I closed and re-opened I get the message. Any help, please?!
We can't know. You are losing yourself in vague and generic descriptions without providing any hard facts like what program you actualyl mean, system info, relevant program-specific settings, project/ file settings and whatnot. Since this is presumably Premiere pro, ask in their forum and by all means provide al lthat required info.
