The racial point costs have been modified so try starting with 5000 racial points so you can load the file and then edit your empire from there.
Note that it will probably be a much better idea to create a new empire for the mod because there is a bug that will reset all tech levels to 0 and stuff like that.
I already re-created the race for the balance mod. So far, so good. The more I play, the more I like. Some quibbles with the interface from time to time.
