Every time I want to open a document I've done in InDesign always appears an error message telling that the DOCUMENT FRAMEWORK.RPLN can't open and then I have to upgrade my plug-ins or my InDesign version. My InDesign is CS and I already did not only the upgrade from the HELP menu but all the choices from Adobe website and they give some tips like trying to open and saving in another format and so on. But how can I open if the program doesn't allow me. The other options like compatibility with versions is OK since I am opening a file done with the same software. What else can I do? Please give many options but not the ones from the website so I can try and figure out.
