[Solved] audio clips not showing up

I'm having very hit and miss results with dropping audio clips (wav files) onto the timeline.
 
Some clips show up on an audio track, where as other clips fail to appear (despite a "conversion" progress bar showing briefly).

Here is an example of a file that did show up

General

And here is an example of a file that didn't

As far as I can tell, the format is identical.
 
I just bought these professionally recorded files and they seem to be the most problematic, but they are not the only wave files that X3 won't accept.

I am running Sonar X3e (Build 244) x64 on Windows 7 ultimate Sp1 with a Behringer UFX 1204 interface (firewire) using ASIO.

Turns out exactly the opposite was true.
I had that box checked already (must be the default), and when i unchecked the box, I seem to be getting reliable imports now.

Cheers.
 
 

I also had to uncheck that box when some .wav files I was sent ended up at something like measure 1200 after import. Couldn't find a reason for it and the .wav files imported as expected in other programs.

In that set of stems, the kick track seems to be missing the extra timing info.
When i import the set into reaper, the rest of them lock in just fine and then I always have to go an fix the playback rate for the kick track. I think it's a descrepency on the part of the sound library vendor.
 
In sonar, with that option enabled, it wasn't that the items showed up way up the timeline, they just did not show up on the timeline at all.
