How do I move to paragraph pieces together in MS Word 2003?

You can see on these two screencasts that the first part of a Word-document in MS Word 2003 is too far from the second part:

That is, I think there is some kind of break or something that doesn't allow the text to flow freely and naturally. I tried the backspace button on my laptop to move the second part up a bit, but the white area (no text in it) in the Word-document is "dead area", not possible to write or enter anything in it.

Overall, in this whole Word-document, there is a lot of problems with the formatting. I tried in my translator tool SDL Trados 2007 to translate in Word but many stretches of text could not be opened as translation segments (in other words, SDL Trados does not recognize the text as such, or can't handle the formatting).

I earlier made a mistake and downloaded a trial version of MS Office 2010 Plus (which I found out later does not work with my SDL Trados 2007, only MS Office 2003 does), and had this installed on my laptop at the same time with my old MS Office 2003. But initially I did  not have any conflicts whatsoever, could open Word-documents with both of them. But now, I have uninstalled MS Office 2010 Plus and kept only MS Office 2003. Perhaps this could have caused the troubles with my Word-document.

Back to my current problem: How can I move the two pieces of text together so the text flows naturally?
