So you ran the Mod Installer and installed the BtS version of Blue Marble into the CustomAssets folder in Civ4 vanilla? That should have had zero effect on BtS. The worst that could do is to bork your Civ4 installation, in which case you can revert simply by trashing the ~/Documents/Civilization IV/CustomAssets/ folder.
I have no idea how BtS installs, but if it follows the pattern of Warlords, I would guess the installer creates a new folder called Beyond the Sword in your Civlization IV application folder, and when you run BtS, it creates a folder in your ~/Documents/ folder with a name like Civilization IV Beyond the Sword. If you can't think of any other action you might have taken that you can reverse, I suggest moving these two BtS folders to the trash (or to the Desktop if you think you might want to revert) and reinstalling BtS from the DVD.
Hope this helps
Actually, it did, because it gave me the idea to delete the BtS prefs, which did the trick. I still have no idea what could have caused the Tech Advisor screen to pop up whenever I started. Anyway, thanks for the quick responses. Now to CAREFULLY install the Blue Marble Mod...
