the situation is this. Large file multiple Xrefs and saved down to 2004 from 2008. archived drawing works but current drawing with a good deal of hatch dose not. Only gets "Fatal Error: Unhandled 0x4b67622 Exception at 332bb0a5h." Looks like its close to opening. In other words I see a portion of the drawing then the error code. The problem happened the other day so I went back to an archived drawing and redid a bunch of hatch and plotted. I come in this morning and the same issue and fatal error.Our client can open the drawing in 08 but we cant in our 2004 lt.Any input on the error code or where I can find help would be great.
