Roll back to X1C

Is there a way to roll back my Sonar X1 from D to C? Did some searching but did not find a clear answer.

Thanks!

Hey, mudgel. That's what I was afraid of. But thanks for the information.

X1D has just been way buggier for me that B or C. It's like it's possessed sometimes. For example, as we speak I'm working on a session made up entirely of Midi tracks. Playback of the session sounds great. I decide to export to audio. I do a "select all". Nothing gets selected. Nothing. I click on any random clip to select it. I then click "select all" again - this time it works. I then export my file to an audio track. Playback becomes an adventure. String parts or brass parts jump all the way up in volume. And not the entire tracks, or even entire clips. Just sections. Maybe even one or two notes. Other parts will disappear altogether. Today I tried again. At the end of the project I have each track fading. For some reason Sonar ignored 1 track's fade automation. All tracks faded - except 1 violin track that just kept blasting. Also delays are unpredictable,  particularly any rhythmic, tempo based delays. They get out of tempo. At first I only noticed it when fast bounce was selected, but now it seems to happen regardless. So - as you can understand - Sonar is kind of becoming useless to me right now. I never noticed any of this with C, so I thought a roll back might solve my problems. I do have a support ticket entered, so perhaps this is something Cake has seen before and can offer a solution.

Thanks for letting me vent!!! I feel better. Still love Sonar, but frustrated at the moment.

Win 7 64bit. Just to test it - I tried the session in both X1 32 bit, as well as X1 64 bit. The problem occurred on both.
