Seems this worked: @jomismo I never had that problem until last night when I reinstall everything. I notice that if you try to use this mod without having played at least once without mods it will not work. It need at least one clean save.
My guess is that "TypeError: Object # has no method 'getDataStore'" means that GDT uses MySQL, SQLite, or some similar DB and it need a save to extract the money value, so if you don't have a clean save it will not found the right value, or position, or something like that.
So, to fix it, just disable all mods, start a new game, make a game, earn some money, save game, enable all mods, exit GDT, start your new game with the mods you want enabled... It worked for me!

Also, on an off-topic note, how long is optimal to wait between game and sequel to get great ratings?
