If you're using a non-English version of your operating system, it's quite possible that you have "special" characters in some of your data paths. Or your name, for your user profile folder, may have e.g. an accent character. TG2 doesn't currently support these kinds of characters in paths, so if you're referencing objects with full paths, this will be a problem. One way around it is to use relative paths and keep your objects in subdirectories of the folder you're keeping your TG2 files in. Another option is to put your objects and textures in a folder that is a subdirectory of your root drive, e.g. C:\objects\. Also avoid spaces, particularly in texture names.
Better support for a wider range of characters in names will be available in the future.
