I have the latest 2026 SP2 program, and some DWG files with a map background open, but the model is black—nothing is visible. The "Edit/Select All" command crashes the program. After opening the file, I'm in the correct location according to the coordinates. On the "Layout" tab, I have a table from a map created by a surveyor and a white background—the map isn't loaded. I should add that the map opens correctly in other CAD programs. I need urgent help.
