I recently clipped a red media clip in redcine-x for a client and sent the file to them via wetransfer... They downloaded it but when they tried to open it in redcine-x their end it said it was offline.
I have seen a clip showing offline before when it was previously saved on a newer version of RCX than what it is being viewed on. Are both version the same build? I would check that, it sounds like the clip is being seen, just not being played back. Does the client have any other program that would play the file? If it is not playing back in RCX it might not play back on anything else...
