Ok guys after a bit of work last night I think I may have a work around for this seems to work for my problem just need to open cod4 player settings and add cod4i in the blank field see attached image cant remember ever doing this in the past.
Sorry if the image is at all blurred it was late and I wanted to post it from my phone

I was able to view the demo but i rolled back my update to 17.9

But by rolling the update back wont that stop access to 24/7 server
I have also found that although I can play demos with my alteration they play at random lengths and sometimes just stop with another error more investigation required

I installed the new update this morning and did as you did placing cod4i in the blank field however of the 3 demos i took none of them actually played. Just got the demo had ended screen. Rolled back to 17.9

What's the procedure for rolling back is it easy gonna roll back later after work.
Some of my demos worked others just finished after starting some ran a longer while and then just ended so roll back coming up

Under this new update 18.1 I can't record any more, but as said if you roll back i wont be able to get into creek 24/7

Mad Dad said there be a patch soon:o

just did a demo on 24 7 and this is what I got today arhhhhhhhhhhhhhhh

tested swing on tdm and this plays
