Damon,
I understand your issues and import and export for the drivers and profiles have been on our cards for some time now, but have never received enough priority. I hope we can get to them soon.
In the meanwhile, you can go to the following location within your old workspace: \.metadata\.plugins\com.genuitec.eclipse.sqlexplorer and pick up the 2 xml files you see there. Replace the corresponding files in your new workspace with these files. Make sure the new workspace is not in use when doing this. When you next start eclipse with the new workspace, the drivers and profiles from your old workspace should be visible. Please note that any of the drivers and profiles you may have already created in your new workspace will be lost.
Sorry for the inconvenience,
Brian.
