Export and Import not working Airspaces or VHF

Since I'm trying to update the Airspaces in Aus, as well as the VHF frequencies, and the OpenAir format is not working. I thought I'd try the Import/Export options for Airspaces and VHF.
The "internal" format, the only one available seems to be XML, but it contains no useful information. the VHF version seems to contain the ICAO/Name only and nothing else.
The import supports the internal gic format, but attempting the import defaults, shows no available files, so not sure what format that is expecting.
Any assistance would be greatly appreciated.
