Sandip,

Personally, I always use ftp to put things on a webserver with my ISP. And I never have seen any message about 'not valid doc file' from ftp (and moreover I'm sure it doesn't ever give such an error message).

I'm afraid this MS Office forum will not be able to help you with Acrobat. However, as it is a paid product, you should be able to get support from Adobe.
