Yes. I removed the old savegames (and the modded ini-files) and startet a new game after re-installing. Worked fine on Patrician IV, but when I startet a new game (the old savegames and modded ini-files were still removed) on RoaD the error occured again. I patched up to 2.0.4, startet another new game (still no old savegames or modded ini-files), but the error occurs every time.
Would be very happy if someone were able to fix the error since me and my brother bought RoaD so that we could use the multiplayer feature.
