Well this is strange.
Do you have ASIO4All installed on your computer.
What soundcards do you use?
Can you send a screenshot of your Audio tab in the Preferences Menu?
We need to sort this out, because Audacity uses a pretty "morbid" way of storing audio, and not only it messes up most of the time, it eats a lot of your system performance, while Cross recorder works as it is not activated.
Stupid question: DO you know where can you find recorded audio?

I really want this sorted out!
