I've downloaded the missging files but still same error.
Also, what can I do as viewer in demo ?
Exept clicking enter which give another angel to watch ?
Let's just try starting from scratch and see if any of the basics were forgotten.
1) Take a new demo to be sure your demo file isn't corrupted. I assume you're using jaymod.
2) Download Sunlight's demoviewer
3) Put it in your enemy territory folder and start it
4) Click 'mods' on the left, in the middle
5) Double click jaymod
6) Click replays (left)
7) Double click the demo you have just recorded
Do you succeed at viewing a demo this way?
What you can do: I'm not the best person to help you but I can tell you a few of the basics.
-Increase your speed by putting /timescale >1
-Decrease your speed by putting /timescale <1
-See trough the walls with /r_shownormals 1-5, undo by r_shownormals 0
-Take screenshots, view scores etc like normally ingame
-Unlag the demo by typing /demo_unlag (ping) into the console
-Much more, but this might be a start.
I know it's a lot of basic stuff, but I'm trying to figure out what part of the demoviewing is going wrong. Fire if you have questions and I'll hope to be able to answer them.
