After inspecting the files you sent us we can say that the system is running out of memory when trying to export your business space version.
There is a way to allocate more memory to the Configuration Tool on startup. There is a startupOptions.props file located in the SAMPLES directory of your Aware IM installation that you can modify and place into the BIN directory to let Aware IM use the startup options specified in this file.
By adding the -Xmx128M option to the Configuration Tool startup command line you can override the default value of 64M. You can increase this figure further (up to 256M, for example) if you have enough memory on your machine.
Please let me know if it helps.
