It should work right out the box.

It wont work with Mugen 1.0. This only works with WInmugen Plus.

What version of windows are you running?  I have run into instances where i couldnt open mugen cuz i didnt have permission to do so. Even if i was on my main account. Im not saying that is what is wrong here, but it is a possibility.

If you go though all the steps and still cant get it to work. I would download a fresh Winmugen Plus and try to transfer the screenpack over to the new one by copying the screenpack files over and then altering the system.def in the new winmugen to point to the files that youve copied over.

You really shouldn't have to do this but its worth a try.

I would try everything else before doing this.

I don't think this screenpack will work with the new Mugen 1.0.

I would download Winmugen plus and try to move the screenpack to that if you'd like.

Here are a couple of suggestions.

-Make sure all of the files are in their proper folders... Data Chars.. ect.

-Download a fresh Winmugen Plus and copy that system.def to the CMS game and see if that works.

-Sometimes the game has to be run as administrator on your PC. It has to do with permissions on some windows based machines. Try right clicking and running the exe as administrator. Good luck.

Do you get an error message? What happens when you click the .exe? Please explain.

QCF=Quarter Circle Forward, aka 236.  I figured everyone who played fighting games knew what that was.

That's all I'm gonna say.

let me rephrase what he is saying, its rude to ask others to updatesomething or make something, if you cant do it, tough luck, just wait for someone who can,
also what gill is saying about the warehouse, is that its online at the author's site (although you probably didnt know that) but its the  same thing. 

No.
Plus why link to a crappy warehouse when he's still at Ahrimanes' site?
