I need a bit more information to help you. What language are you using? Java?
Also, what platform are you on?
On Windows TurboActivate looks for the TurboActivate.dat file in the same directory as the TurboActivate.dll file. On non-Windows platforms TurboActivate looks for the TurboActivate.dat file in the same directory as the executable that uses libTurboActivate.
On every platform you can explicitly tell TurboActivate where to look for the TurboActivate.dat file using the PDetsFromPath() function.
