Have you tried Tesign's suggestion? It sounds a bit strange, but basically it is this: 1 - back up your current Vue and all sub-directories just in case of problems. 2 - UnZip the original Red Coral. Move the Coral files to the Plants folder, and move the Biosphere#.DLL to the main folder. 3 - open Vue, start a new file and attempt to load any vegetation. At this point, Vue should tell you it's found a new one: Red Coral. Supply the key number for it to install. 4 - load Red Coral. If this works, you'll need to again replace the Red Coral biosphere#.DLL with the current Biosphere3.DLL. Please excuse my ignorance of French. :)
