layout changes not reflected in adobe form.. ?

`I copied the standard adobe form to z adobe form ....as i had to make some changes in the layout ..

First time i made the changes it was successfully reflected in the output but after few days for some other requirement

when i made the changes in layout it was  saved and activated successfully but was not reflected in the output...

I have activated it many times but it is of no use ....the print preview is coming in older version and not in the active version..

what could be the reason.. ?

Thanks in advance..

Regards,

Ankit
