We can't ship an MP3 encoder in the States due to licensing restrictions on the proprietary MP3 format. (It's patented by another company, and it's not cheap to license at all.) However, we can build the app against a Universal Binary LAME encoder, and as of 3.0.4, that's available for use. Please see http://www.freeverse.com/soundstudio/ for a Universal Binary LAME framework that is compatible with Sound Studio 3.0.4.
This VT listing should be for 3.0.4 within the next few minutes.
As for registration issues, we can't address the issue directly if we're unaware of it, I'm afraid. Please contact support (support@freeverse.com or just give us a call, we don't mind) so we can get your registration issue straightened out ASAP. It's usually not a difficult problem for us to resolve.
