No, no I didn't say you have to delete the retail vp. If you really have the retail vp when you installe your Freespace 2 SCP within fsoinstaller, so just let them here and just play. But, When someone tell me that he has the same problem as mention here, I tell him to take a screen of his Freespace 2 root folder and I see there is no vp file there but only in his mediavps folder which was in fact the retail build or perhaps a modify retail vp with the latest mediavp. Well I don't know since I use the original game. And in his screens, I saw that his freespace2.exe was the launcher (just display a more detail view in your explorer and you will see this.
So, I've just tell him to move his vp files from his mediavps to his root folder and it work but the training seem to crash after some second. Then I didn't have any new contact of him. Si I suppose he is playing a lot.
