This item has been identified as an outstanding known issue. A workaround is provided until the issue is officially fixed.
When a module goes over 2^31 (2,147,483,648) cell count, Excel Add-in Version 3.1 doesn't allow you to select that module.
The Next button will be greyed out.
This issue no longer occurs in version 3.2 of the Add-in, however it can be worked around in previous versions by reducing the module cell count to be below 2^31(2,147,483,648).
If this workaround is not suitable in your use case, please contact Support at email@example.com.
