It sounds like you have already been importing projects in the past, but just in case- here are some step-by-step instructions: https://answers.blk360.com/en/article/how-can-i-transfer-my-project-fro….
I would suggest trying to create a new project in Register360 and attempt the import again. If that doesn't work, it might be worth contacting our technical support at [email protected].
As for the image- I'm not exactly sure what you are referring to? Have you taken a screenshot in the app? Or are you talking about the 360 pano image of the scan? If you have transferred the scans over to Field360, you don't need to be connected to the scanner anymore. All of the BLK360 data is on the app and you should be able to view in 2D or 3D and do anything that you need to without connecting to the scanner again.
