When I'm trying to edit the title block in Project Setup dialog box (using Setup Title Block ... button) it displays an error dialog box and does not open the template.
It was working fine till yesterday and suddenly stopped working.
That happens in one of the projects and there is no problem with the others.
Here is the error dialog box.
What should I do to fix it?
Which template are you using? Sounds like that particular file may have got corrupted. Try replacing that template file and see if you get the same error or if it goes away.
I just use autocad created title block with all the attributes and stuff - works like charm! just create your own template - copy from Autocad drawing.
