Twofer: 1) Got a BSOD after closing SPlat then opneing Pyro 2) Loop Record corruption

Hi, all. Everythings fine (I think). Just had a couple things happen a while back and wanted to pick your brains before I forgot.
 
1) I had exported a wav out of Sonar Platinum. It was just intended to be a song segment but it ended up being longer than I wanted (I screwed up). So instead of reimporting/starting a new project I figured I'd snip it down in Pyro Audio Creator. I opened the wav with Pyro (this was maybe thirty seconds or so after closing Sonar) and began playback. I immediately experienced a Blue Screen o' Death. I have never had one of those before (or since) so just wondering what may have been the culprit. I'm guessing the audio driver/interface went screwy somehow but Beeped if I know what happened. I ain't no tech.
 
2) I was recently working on a CWB that was not really ideal but was working more or less okay until I did some Loop Recording. It was created in SPlat and I was recording into SPlat. After I did a bunch of passes with Record and Looping enabled (which recorded fine) the project started acting funky. Timeline started turning black (the white overlay graphic disappeared), Playback would not start reliably, started getting Audio Engine dropouts, etc. I kept closing the project hoping that would help, it didn't. I rebooted, that didn't help. Eventually the project became unusable. This was audio being recorded (guitar stuff) and they were just scratch/practice tracks so no biggie. I reverted back to an earlier version and rerecorded without Loop on and everything was fine (more or less). I never really use Looping while recording because it caused me problems in the past (in X2) and the symptons were similar. I've read about Loop record issues but they seem to be about MIDI stuff and things going out of sync. Just wondering if Loop Recording is causing anyone else any problems and if so what kind of solutions have been found. I'm more interested in diagnosing potential system/stupidity issues than actually using Loop Record because I'm fine with pressing R... I was just doing somehting specific where looping was beneficial.
 
Anyhoo... no emergency. All in all everything has been working fine so far with SPlat. I'm just curious.
 
Sorry I haven't been around the past few days and I may not reply right away. Haven't been logged in because I'm not feeling well and am kind of preoccupied but will be watching and hope eveyone is well.
 
Cheers.

I'm thinking there was some kind of interface (or maybe a combo of interface and onboard) driver freakout when I closed Platinum and then opened up Pyro. As I said I'm no tech but obviously peruse many forums and have seen these issues mentioned (but don't really understand them).
 
I did also recently change my video display settings and updated my Korg padKontrol drivers. Other than that, and installing Platinum, there have not been any changes to the system and I used to be able to switch between Sonar (X2/X3) without issues (but could not have both running because I have everything set to ASIO).
 
I'm doing some work (in between being a sick weirdo) but after that is done I'll be doing some hardcore maintenance or perhaps a full reinstall of everything. I really hope this isn't a hardware issue. That would blow.
 
Thanks and...
 
Cheeeeeers.

thoughts regarding (1) does pyro behave itself usually? (i never used it, i have the sony apps)... are you set to "share drivers" in sonar? did you try & repro? could sonar have been still "shutting down in the background" when you launched pyro? etc
good luck
