Rosetta Stone doesn't work?

The speaking section of the program, (in my case spanish) is terrible. I have to say a word or phrase many many times and if often still doesn't work. I've found that changing my voice to match certain cartoon characters often helps. When talking as an angry Vegeta or just regular Kermit The Frog I find the voice software understands me better. ... ... ARE YOU READING THIS?!?!?!?! I have to alter the sound of my voice to proceed with the lesson. Rosetta Stone may work but I can't get further in the lessons because although I an enunciating the spanish word perfectly the software chooses not to recognize that I am speaking correctly. Before any of you morons out there tell me it's a simple fix i'll let you know I have tried 3 different microphones, I have tried using the program on both my laptop and home computer, I have eliminated background noise, I have increased background noise (fans, vacuums, air conditioners, etc.) and I have let otehrt people say the words and phrases, some of them even speak spanish and nothing seems to work. The program is broken and unless I get an answer or a fix I'm just going to return this garbage and get my 300 dollars back.
