We cannot open any of our newly created DWFs! Using the DWF6 ePlot.pc3 driver, the same one we've been using for two months now, any dwf file created gives us this error when we try to view it: "Autodesk Express Viewer Error. The below error has occurred. It may be possible to continue, however the program may become unstable. Error: 001-2147024809." Pressing either of the two buttons, Cancel or Continue, results in nothing - the dwf does not open. Same result w/ any drawing, even a new blank drawing with only a rectangle in it. Preview looks good, no crash in acad. Happens using Publish or Plot. We're on win2k, have 2004 sp1a, IE 6.0.2800.1106. Thanks.
