Can you make a X-Men version of this?

Ok, I just redownloaded it and all, and it worked right away. What are all the files you have in your "Media"folder? You should have:

l4d2_background01
l4d2_background02
l4d2_background03
l4d2_background04
l4d2_background05
l4d2_intro
l4d2_upsell
startupvids.360 (text document)
valve
valve_xbox_legals


All of the above are .bik files, with the exception of startupvids.360, that's a text document file.
If you have all of the above installed, then maybe you should redo the installation, as i'm not sure what else might be wrong, maybe other add-ons are affecting it? Not sure that could happen with a media file though, unless you have other media file add-ons.

I'll redownload the mod and try to figure out what might have happened, because that's strange, as it works for me and everyone else, not sure what might be going on.

Yeah, I know, that what surprises me, 'cause I did everything as you wrote, and no, I did copy right files from mod, and there are no original files, because they re in folder at dekstop

Are you still seeing the same standard background video at the main menu then? I'm thinking you might have accidentally moved the origanl files back into the "Media" folder. It's either that, or you moved the files from the "Backup" folder into the "Media" folder. The only files you should move into the "Media" folder is the contents from the "Mod" folder. It's easy to accidentally copy the wrong files. Also, make sure the original files you had in the "Media" folder are taken out of that directory, and put it somewhere like your Desktop for example.

five l4d2_backround01 files, last parts renamed into the numbers and other stuff

Ok, se, what do you see in the following folder?
C:\Program Files (x86)\Steam\steamapps\common\Left 4 Dead 2\left4dead2\media

I did all the steps, but it's not working. What should I do?

Hey, just got your comment. Here you go:

Just subscribed to it myself to test it out, and it's fine and working. Actually thinking of keeping it as my default song now haha. Thanks for the suggestion. Enjoy.
