Upgraded GeoBase not finding any data files

After installing a Geobase upgrade over an existing version of Geobase (for example, upgrading Geobase 2.7 to 2.8) you may get this error when you try to run Geobase:

Could not find any data files

The default location for Geobase data is:
Program Files\Telogis\Geobase\Data\

If you install Geobase 2.8 over an existing Geobase 2.7, this \Data folder will contain two folders, gb.2.7 and gb.2.8

Geobase 2.8 looks for data in the gb.2.8 folder. You can copy (or move) the existing GBFS A methodology of storing spatial data for optimal performance in geospatial or location-based applications. For more information see the GeoBase File Systems FAQ page. files from your \Data\gb.2.7 folder to your \Data\gb.2.8 folder
