Hello couldn't upload the newest update was thinking my ST16 wasn't reading my SD card. I also get Bata expired . I haven't worked It much but feel this is the program I want and need for the work I want to do . Think this is great work and the main reason I purchased the H is for Mapping and land contorting I was thinking I made the wrong choice until I saw this program. I just hope I can afford the full program when Tuna decides how he is going to market it
