I followed instructions in the pdf file on the first page of this topic and I made a nice pdf from doc. I call this doc file also a valid doc file because I could turn it into RTF that the reader can read.
Then I decided to convert another PDF into sony pdf. First of all I converted pdf into doc then proceed as in a previous example. However, something is wrong with doc file that I get after convertion. I also cannot make RTF file from this doc. Connect would not transfer it to reader, it would hang. When I try to set margins in Word for this doc(as described in the instruction and worked for a valid doc file) it says that the margings I set up are too close to something or too small I don't remember. I call this doc file - invalid file, and I think the problem lies within PDF->DOC convertion. I have used different applications for it. I think it is not a problem. Just this pdf file is a bit odd.
My question is, whether I can edit in Word this invalid doc file so, that I can make a nice pdf?
Please do not suggest BD and similar application that loose text formatting during conversion, i.e. they convert PDF into simple TXT before they make another file. TXT loses any rich text formatting like italic styles.
So, I would like to edit in Word the invalid doc file which manges to retain all the nicities of PDF.
Is it possible?

Gosh, I hope I explained myself clear enough...
