BIMx stops responding during upload

[svpribyl]

I'm trying to upload a BIMx file and ArchiCAD stops responding. Sometimes it will start again after a few minutes, but most often it just stops completely and I have to relaunch AC and start the upload again, hoping for a better outcome. The file is less than 100MB.

Apparently one layout causes it to stop. It's a layout showing several sections. If I delete the layout from the Publisher set, it works better. It's still slow, but better. Does anyone know what might be causing the issue with the sections?
