When I click on button it asks to download the file.The file size is 3Mb but while saving it shows just 25kb.When I save it and try to open it, it gives the following error.
Adobe reader could not open file because it is either not a supported file type or because the file has been damaged(for eg it was sent as an email attachment and wasn't correctly decoded).

Can anyone help me on this.

thanks......
