Sorry to hear you had problems with the component dagnome.

If you post on the support forums I will be happy to walk you through how you can get around any problems you are having.

For those with similar issues, there a several work around on the export content support forums for sites with a large amounts of data or if they have all their data in the one section.

The easiest method being to break your data into smaller chunks by created a dummy section and then using the copy feature to move category(s)into it.

Then simply compile the new smaller section.
Note: After installing the data on the destinations site Export Content will allow you to set your new site structure up anyway you see fit.
