Having 6.4 up and running is the first clear step...now, if you have plugins such as Waves, you will most likely need to reinstall them, however, they may show up in your Inserts and/or Audiosuite folders. 6.1.1 to 6.4 Waves do not need to be re-authorized as far as i know. what other plugins and exactly what are you trying to load anyways? ev
