my WMZ file doesn't work

I can't make a correct WMZ file
I made a skin for wmp9,
all the .bmp and the .js and the .wms are in one folder.
I zip the folder with winzip8
then change the extension.zip to .wmz,
I put the wmz on wmp9's skin folder.
then in the skin browser of wmp9 when i choose my skin
something made of empty pictures appears but not my master peace of sh...!!!!!

note : if i double click on my WMS file(in my skin folder) wmp9 come with my skin so it's seem's that there's no problem with my skin itself.


please somebody can tell how to make correct WMZ file and don't say just "use winzip", it doesn't work.

thank you. Peace, Funk, Unity and have it Fun !!
