DigiVis 500 - "reading metafile failed"
I can't really help You with the crush, but I will tell You what You can do. Just import one bitmap - it's good practise to create full static image for FGR and the create a single bitmap of it. Then You delete the elements and replace them with a single bitmap on which You later put dynamic elements.
In Your case You may either build the static in Graphic builder or any other program. It may require doing a few steps (adding elements, creating a bitmap, replacing, then adding some more elements and creating the bitmap again, etc.) if You decide to use GB for this.
Hope this helps,
