Dear sir. I’m writing to ask you a favour. I’m having a problem when using your programme “LibreOffice Calc” I made a very important project on your programme. But when I supposed to finished it, there was something wrong. All symbols in tables turned to ? question marks. I’ve spent a lot of time for this project. Unfortunately, I am not able to do it again. Could you help me with this problem? Thank you so much. I have “windows 8.1” Program “LibreOffice Calc” v.5.2.2.2, language russian and english .
