You can change the file type of the file to .txt to convert to a text file and then upload it. Please include what the original filetype was so that I can correctly convert it back.
As for the GEngine line, this may have caused an expected crash depending on when it was used/called. If you added that to the constructor of a class then the crash would be expected since GEngine would be null. It would be best to add an if(GEngine) line before you call AddOnScreenDebugMessage() to ensure that GEngine is properly set.
