libre office crashes when saving from .docxs to odf

This is my first post here and, although I have read the Survival Guide, I might have done something wrong and I apologize in advance.

Im running Windows 8.1 圆4 and the newest LibreOffice version for that platform. I have tried reinstalling it, I have tried cleaning the register and I have tried running it all with an administrator's rights. Now I found out that all the applications included in LibreOffice crash at saving files.

However, today I updated the whole software as I'm going to have to use the word processor for professional purpises and, unfortunately, I have to save my files in. A few tries of reinstalling it did not solve the problem, but I did cope with that and got used to. As a matter of fact, the previous version of the software crashed only if I saved files in. It crashes every time I save a file, regardless of the filetype, saving location or application used.

Anyway, after I reinstalled my Windows I can't use the program anymore. I've been a fan of LibreOffice software for quite a long time.
