Libre Office can't open any full PPT file

After updating to Libre office version the Impress module do not open a full PPT file. It opens the first page only, and no other pages are visible/available. It is like a single page presentation.
I cannot remember from which version I updated, but I had no troubles with previous version concerning PPT files.
The PPT fileas in question are created using either Libre Office Impress or older version of PowerPoint. Both unaccessible. The older Power Poin opens them without any difficulties.
