That demo played all the way through okay for me without RypelCam, using a DemoManager version from 2016, udemo.u is 301 KB and udemo.dll is 143 KB. Usually my demos recorded on that server will crash in the middle, supposedly due to problems with NewNet. But that's a separate problem.
Just did a little test playing the demo back with the DemoManager version included with RypelCam and it was fine. It's only when I go to Mod > Demo3+LoadCam that it crashes.
Looked through the cache files and it looks like one of the cache files might've been updated between when the demo was recorded and now. Here's a more recent demo if you want to see if this one plays. I know for sure it crashes about half way through.
