Hi. Weird problem. I've set up my machine months ago to connect to SDE 9.2 from Civil 3D 2009 and it's worked all along. Recently, however, it stopped working. I can connect and view all the layers the same as before, but when I select a checkbox beside a layer to query and hit either "Add to map" or "Add to map with query", the button greys out and nothing happens. I'm lost. This has worked on this machine for months (even with 2008), but now it stopped. As far as I can tell, nothing has changed with SDE either. Is there a log anywhere I can view for errors? Anybody else have this problem?
