How can I add voices to TSS 7 director?

I got the program TSS 7 director, but I'm also a Spanish speaker person, so I also got this spanish voice pack for Loquendo from a friend. The pack says it includes voices from Jorge, Carmen, Carlos and Soledad. I installed them but the voices don't appear. When I tried to repeat the procedure, the files for the voices went to the folder '\loquendo\TTS' but the voices already installed in English are in the folder \loquendo\TTS 7. I think the problem is the voices are going to the wrong folder, but I don't know how to fix it or where to ask, since I got the voices on a loan. Can anybody help me?
