There should be a seamless transition from the end of Ego Draconis (after the Hall of Echoes) into Flames of Vengeance (back to Aleroth).
How long did you wait? There can be a bit of a delay on some systems.
Can you start a new FoV save? (to determine if the problem is with the start of FoV or the transition itself) You existing autosave may get overwritten, but other saves would be fine.
Try installing the
AC3filter audio codec.
Try setting the game resolution the same as your desktop resolution, and see if that helps (
Crashing during opening of Flames of Vengeance...). If not, try lowering both the game and desktop resolution temporarily, to see if that will let you get past that point.
You can try temporarily running the game in windowed mode, and see if that lets you get through the transition (see
Crashing between ED and FOV).
