Hi Ashley
Well I got import a file I created in Tiled when I drag.The file has just one tileset and 1 layer.But I imported a tmx file to TILED from a program iTileMaps, from iPad.Well it was imported to Tiled nice ( in native tmx) and saved again in Tiled.So I tried drag in C2 but I had this message:
"Error parsing XML file.Check the file is a valid Tiled TMX file."
The file have 2 tilesets and 2 layers.
