Control data of fem input are not available

When I try to load large DAC (result) files of around 4 gig an error occurs "Control data of fem input are not available". Is there any current solution to opening this file?

Thanks in advance

Garth,
There was a bug related to the saving of large DAC files in version 6.000, which is the DVD version (bug number 1). In any patch for version 6.0, this bug should be fixed (see http://www.feflow.info/forum/index.php/board,4.0.html).
