Object reference not defined for one instance of an object

Question

Dear all, 
 I am having a problem while opening a pptx file. 
 Every time I load it, I get a message that reads something like "Object reference not defined for one instance of an object" (in portuguese). 
 I have seen some possible solutions deleting files in an AppData file, but I cannot find that file on my computer. I am running Windows 10, using Trados Studio 2015 version 12.0.4961.2. 
 Thank you.
