can't open powerpoint files

[telamon.raptis]

I can't open any powerpoint files though I have PowerPoint 2013 on my PC.



I cant open presentations that I created couple days ago, more old I can.

What would be the problem with these .pptx files?

Try this first and see if it helps:

1) Go under the Format Menu
2) Choose Replace Fonts
3) No matter which fonts you've used, replace them all with a standard one (Times New Roman) is probably the safest.
4) Try now "Save As" under a new name
