maximlebedev Posted January 18, 2015 Report Share Posted January 18, 2015 Dear all, I'm using Windows 8.1 and always have the same error message while trying to open any .ptm or .rti file (including, for example, Ban-Papyrus_1000) in RTIViewer: "Opening Error. Internal format unknown". I will be extremelly thankful for any suggestion! With best wishes, Maksim Link to comment Share on other sites More sharing options...
