I am having a problem in AutoCad electrical with the update/retag utility. Every time I click the update/retag option in the project tab, I am given "Error: bad argument type: stringp nil". I have asked around here at work and neither myself nor anyone else I have talked to has any insight on a way to remedy the issue.
Those type of errors can happen from time to time. Usually if you close the software and restart it, the problem is corrected. Sometimes you might have to reboot your PC. This is a very rare occurrence, so if this is happening often you may need to repair your installation. Also be sure that you are running the latest service pack or hotfix for your version of AutoCAD Electrical.
