Hi John,
Thank you very much for your interest and will to help, I truly appreciate it.
I also guess there must be some kind of conflic with the codecs.
The codec of the output video from that project file is H264 - MPEG-4 AVC
(audio: MPEG AAC, mp4a)
When I try to open it in a new Windows projec, it gives me the exactly same error message.
