Can't import simple wav file into new cakewalk sonar free ver

[LNovik@aol.com]

I switched to Sonar free version about a week ago. Prior to that, I was easily able to bring in a wav file into my project. Today, I again tried. I did it with the regular "import" option from the File pull down menu. And then I tried it by simply dragging the wav file into a free audio track at the bottom of my other tracks. I actually WAS able to very easily do it. However, when I did this, every track above it was moved over to the right. So, specifically, I tried to place this approx 8 min wav file at about the 10th measure. When I started to listen, I heard the original project playing and then everything got slient. I then started to hear the sounds from the imported file. But every other track--and there were more than 50 of them, got moved until the point on the timeline where the imported wav file ended. 

Luckily, I was able to move all my files back into their correct position by hitting the undo button. But, of course, I can't import my wav file.

I was thinking that perhaps the file was a different bit or sample rate. But I have to been able to import similar files until a week ago.

Could this be a shortcoming of the new free Sonar? 

Lastly, is there a new forum to post questions to for Cakewalk Sonar users?

Thanks very much for your time.

Do you perhaps have Ripple Edit selected?  If so, that could explain it.
