We have a file that we are having problems saving. The file was originally an AutoCad file containg topo. We successfully saved it in MicroSurvey format (Still dwg since we are using MicroSurvey 2005) and have been using the file for months now. The file has recently become unusable. The problem occurs after we get in the file and do some work, save the file and open it back up again. Upon opening it the second time, when we try to save the file we get an error that says
Error: Invalid Input
Your file could not be saved:
C\jobs2005\......filename.dwg
We are getting this message on two different computers using the same file.
I tried the purge command already.
