Problem with "M+alt" and textures

[Krzyn]

Hi,

I have problem with m+alt.
It should moving in the vertical axis, but when I use this nothing happens :/

I have problem with textures too.
I instaled textures from CD, but when I turn on editor and choose landscape will appear information "You don't have textures in your sourcemedia folder..."
When I do my own map it isn't problem, but when i try edit oryginal map old tex disappear...

I tried reinstalation, but it doesn't help.

Sorry for my english :)
