I do not get the error, but thank you for reporting it. I will double check the Ai files to be sure.
I would suspect that the Vaadwuar Research file is out of date. All of the research files for 1.9.0.2 are the same for each race, just named differantly. Copy over one of the other races Research file and rename it after the Vaadwaur. Should fix the problem.
I will verify that the next update has the correct research file for the Vaadwaur just to be on the safe side.
And welcome to the forums.
