I don't even know what to do :< I drag the tah files on the pedo thing, and nothing happens -.-
Finally!!!, after a day and some hours I think that i have found the solution at least for me. I'll try to explain step by step:
-1º:Download the .zip that i have attached, and save it where you want
-2º:Extract the content into the arcs folder of the game (Example, for me the arcs folder is located in C:/downloads/TechArts 3d Custom Girl/arcs), put the TAHpedo.exe, the TAHDom, the TAHBoin and the source folder in the "arcs" folder, they need to be in the same folder in where the base.tah, and the basexp.tah.
-3º:Right Click the TAHPedo.exe, go to properties, then go to the compatibility tab, then in the compatibility mode put WindowsXp (Service pack 2) and then check the "Run this program as an administrator.
-4º:Once the above steps are done, go to "base.tah" file, right click it, go to properties, and in the "General tab" go to "open with" and select the TAHpedo.exe. Do te same with the "basexp.tah" file.
-5º:Finally, double click in the "base.tah" file, and the process should start, when it has finished do the same with the "basexp.tah".
I use a w7 64 bits, I hope that this will work for you. Maybe i have missed some step dunno
don't want to reinstall the game to check it xd
