HI ,everybody. firstname.lastname@example.org When I open a SHOW document, it will show a mistake like this: Unkown (miscellaneous) file load/save error. This may be caused by the file being saved in a newer version than you are using. Try updating your software to the latest version, found on www.pangolin.com but my LD2000version is the latest version now. some one can help me ? Thanks .
