Environmental Visual Enhancements... does it work?

[Joe Kerbal]

I'm definitely a newbie of KSP mods but actually I've installed various of it (with CKAN and without) not getting any problem.

I'm very confused about EVE - Environmental Visual Enhancements. The mod appears to be installed properly. I saw some clouds then probably I messed something in the config... however I've installed it again and again. I've understood you can use various textures set and edit your own config. Anyway I have no more any clouds and despite I've attempted  installing Stock VIsual Enhancement and Astronomer Visual Pack still looks like I have broken texture reference.

I'm pretty sure I'm missing some very basic thing here. As you can see the link for the texture corresponding to the cloud layer is broken. I just have to link that to a local file? How can I get the right file? why there's no a default config or where can I find it?
