Hi everybody. Some of you may have read about my computer trouble. It looks like I may have solved most problems however Dimension remains. D!J!X! explained to me that Dimension 1.0 has to be registered on a 64 bit system before upgrading. I have the duel layer DVD that came with Sonar 8 and I assumed I was installing Dimension 1.0 but the release notes also mention 1.5. All attempts to register Dimension fail because it's "not properly installed". Any help is appreciated. Bob.
