Unable to open DOC / PPT files

Help! I recently created two doc files and a ppt, but now neither Microsoft Office nor LibreOffice can open them correctly - when they open, all I see is blocks of

Pease help, this is a bit of a disaster for me at the moment!

Please edit your question to indicate what it is you are seeing (as this was cropped in your original question). Also include details about your operating system, LO version, and in which application / version (e.g., DOC created in MS Word 2007 and subsequently edited in LO v4.1) each file was created / edited.

Please follow the advice @oweng gave you.

Additionally I would like to recommend to work always in native LibO format and change the format only when you need to do so. At the beginning I worked a lot in MS Office formats until I recognized that it is more convenient to only send pdf-files. Only when there is no other chance, I convert to other formats after i completed my work.

The globe doesn’t change spinning when formats others than MS Office are used.
