I'm in the 99.9% range of pretty sure its the computer, because we just don't get issues like this with other users. There is the occasional problem with a room deletion hiccupping the polyline files, but this is a lot more in depth - its a failure of the database write back, and that can only realistically happen if there is a problem with the hard drive, connectivity issues, or if the software is shutdown incorrectly (reboot, etc, with project open) - I'm assuming that you aren't shutting down/rebooting the computer with the program open, so that only leaves potential hardware issues.Just do double check a couple of things:Whereabouts are you storing your projects? Is it to a local drive or network drive, and do you store them all in the same sub-folder?Do you have space on your hard drive?Can you recall any other errors? and did an error occur before the 3058 error?Are you using a virtualized version of the software or running it from a remote desktop?A lot of questions, I know.Thanks,
