Addictive Drums 2 Sound Drops out Randomly

There are other threads about this from a while ago but none seem to have ever solved it.
 
With an already prepared Addictive Drums 2 track, the drums will just randomly drop out every so often. I've got a beat with changes and everything throughout the song, and I've both played the song in Sonar and exported the song to wav in the past with no issue. There are also about 8 other tracks from other sources like Omnisphere, Kontakt, etc.
 
But today, when I load the cakewalk project, it's doing this dropout thing. The midi data is all there. It just randomly drops out like as if there are no notes for a couple seconds and then it comes back. It happens in random places. And if I try to just freeze the drum track, it freezes it with dropouts every so often.
 
I have an i7 and 32gb RAM. Loading off an SSD. It's a really powerful computer and shouldn't be running into performance issues, which makes me think its more of a bug. Running windows 7 64bit and Sonar Platinum
 
Any ideas?
 
Thanks so much.

Edit/Preferences/under Audio, "Driver Settings" - - -> buffer size, set to big, like 1024 samples?
 
you probably already tried this.
 
This is the buffer setting I use for mixing. for tracking (recording) I set it as small as I can (256).
