This is the second time this has happened, but the old fix is not working. We have a job that has a lot of hours in it that has now locked up. Last time I renamed the back up file and made it the dwg file, but this time that is not working. I have also created a new job with a different name and copied all the files over to it, but it still won't open. Trueview 2020 requires a recovery to open it, but lacks the ability to save it once it is recovered. Dead in the water now.
