IntelliCAD Crashes on Save

#1
We use IntelliCAD, AutoCAD and AutoCAD Lite.

I am finding IntelliCAD crashes when I go to save a drawing that was created in AutoCAD (mostly likely saved as AutoCAD 2000).

As soon as I click save or save as, I get a error box pop up saying "IntelliCAD 6 Pllication has encountered a problem and needs to close..."

When I close it, the original file disapears and I have to re-create it from the .BAK file.

Any ideas?

Thanks
