I am having problems with the InsertBlock method in one computer. The same procedure works fine in the other computers in the office, as it has been working since ever. Now I am getting this "Filer Error" and I can't figure out why. I created a test procedure(same structure) on the machine in question and it worked fine, so I don't know what is going on. I checked previous posts and it seems like there has been some problems with this method. Has something been done about it? Is there a solution or workaround? AutoCAD 2004 on XP. Thanks for any help.
