IGO rebooting when TTS voice is selected

Hi everyone, I recently added a TTS voice (form the package TTS Pro_English_UK). When I select it from the menu, it doesn't play a sample of the voice (it usually plays sample when I choose a non TTS voice). Then when I hit back, it reboots itself.

Does anyone know how to fix it? I think I copied all the required files into the correct folders but I can't make this to work. If you know how to solve this please comment. Tks,
