eQuest - CAD file error Teigha Error

edit

Hi all, im uploading a CAD file into eQuest version 3.65.7175 and im getting error 'Teigha Error: Invalid file version'

The CAD files open fine, so im hesitant to reach out to the client and say the files are broken. A coworker tried to open the file and still no luck.

Has anyone run into this same issue? Any potential solutions?

Thanks! Best, Greg
