Hey, I bought a USB condenser mic, which came with SONAR LE. It was working fine until today when I tried to export my song into mp3 and a message pops up saying, "The MP3 encoder must be unlocked before use. Please visit http://www.cakewalk.com to upgrade a previous encoder, or to purchase a new encoder." This doesn't make sense, because I bought the USB condenser mic which came with the CD, I didn't buy a demo version. Does it just run out after 30 days even if it is the real version? What can I do? Is buying it all I can do?
