[TYPO3-ttnews] Doesn't show one single new in news detail page

[xescjp]

Hello everybody:

I have one page where I list a certain category of news. This page lists 
news correctly.
I have another that must display one selected new on the previous page.
Each page points to antoher, one to back the list and the other show the new 
details.
When I select a new on thi list I am redirected to the detail page but a 
message appears.
Its shown in my language. It says more or less : No valid id news given.
Anyone knows why this happens?

Many thanks
