solved ... URLs purged

Hi ppl.

I've installed successfully both components on my web page.
I have 2 languages, and every while my index page of both language is changing.

first index of my web page looked normally like this:

www.my-page.com/en for english
www.my-page.com/de for german

then after few hours it looked like this:

www.my-page.com/en/1/
www.my-page.com/de

and now it looks like this

www.my-page.com/en/4/
www.mypage.com/de/2/

when I go to root url

www.my-page/en or /de after these jumps it show 404 error. Or any last level that worked before is not working.

Why is my root page for languages keep on jumping ?

tnx
