Multipsk not seeing my rtl-sdr dongle, why?

Francesco Lancellotta <flancellotta@...>

My multipsk doesn't see my dongle and if I click on rtl-sdr button then a pop up window comes up saying no rtlsdr.dll BUT this damn files are in the multipsk directory!!! 
What's wrong with this software?? Is there anyone who can help?? I tried to post this morning too but I don't understand how this system works
