Great tool, but you should think about edition for users of some eastern europe languages TDU versions. In many cases it doesn't work with them.
I have same problem at begining - i've bought normal version (not gold) of tdu, but when i tried to use TDUMT, it shows bugs like when trying to use it with gold edition.
Solution is easy - replace DataBase folder with version of the En/De/Fr/etc. edition. But then language changes to english.
Maybe you should give users possibility to choose language what they use in game?
It would be great if everyone can change car names, modding physics etc. in their own language game versions.
Oh - And you definietly should add support to gold edition - many peoples buying it because its cheaper than TDU + megapack separately.
