I can use Switch on my XP workstation with no problems. Trying to get the trial version working on Windows 2003 server with no sound card. I have seen that others talk about success with this, but not how they did it. Can someone explain what I am missing on the Windows 2003 server to get this working? Trying to convert .wma to .mp3 I get a Digital Rights Management error. Trying to convert .wav to .mp3 I get a corrupt file error. The exact files work fine when converting with Switch on my XP workstation (with sound card). Thanks in advance for your help!
