About ready to give up on Sonar. Frustration does not lead to creation.

I have spent more time being frustrated with things not working than I have spent trying to create. My latest is that Kontakt Player stops the audio engine until I delete the tracks for it and the plug in from the explorer. I've not been able to use Reaktor either.  And why is it when you delete a track often times the track above is deleted also? Has anyone else had similar issues?

My system is only a couple of weeks old: MSI mobo, 2.3ghz dual-core amd, 2ghz ddr2 ram, 7200rpm hd for xp sp2 and apps, 7200rpm hd for plugins, samples, renderings, It has been tweaked. I did research and optimized it. As soon as Kontakt with 8 outputs loads( before i load an instrument in it) the audio stops working. Mind you this is opening a new blank project with only Kontakt. There is no audio or any other midi track in use.  I'm using asio4all without hardware buffering at 512k, 24bit 48khz for my Berhinger uca202 audio interface. Internet is disconnected also. No vsti's whether from Cakewalk  or not respond to midi even from the piano roll.  Audio and midi tracks get deleted. I understand about track folders. It happens to totally separate tracks.

So, which version of SONAR Home Studio do you have?
Also, this page http://www.behringer.com/EN/Products/UCA202.aspx seems to indicate that Behringer has it's own ASIO drivers. If that is so, DELETE ASIO4All from your computer.
Then download, unzip and install the Behringer ASIO audio driver.
 
Plus, Cakewalk recommends updating to XP SP3, but they have some hotfixes for SP2

Big red flag.
Let's see if we can get the basic stuff running before you throw in something more elaborate.
From what I am reading, you have built a new PC, running XP SP2, AMD dual core CPU, dual 7200RPM HD's. Correct?
So far, so good.
I am going to assume you installed the MOBO chipset, USB, etc drivers.
As Greg mentioned, there are ASIO drivers for the Behringer unit.
Why are you using Asio4All?
Are you sending your audio out to the uca202 or to your built-in sound card?
In Sonar, what are your playback and record timing masters?
Are you open to the idea of installing a more robust audio interface?

I disabled the mobo sound in the bios. I've been sending audio through the uca202. I was using asio4all on my old pentium 4, gigabyte mobo without a problem. I tried a couple of other daw's with asio4all and no problems with audio or midi on this new system. What are playback and record timing masters?

I think I'm closer to to the answer. I saved the project, reopened the program, no midi or audio. I pushed apply in the audio panel. I now have midi and audio. For whatever reason when I open the program I must hit apply in the audio panel. It's very strange. The settings don't change when I close the program.

Did you install the SHS 7 update from Cakewalk when you did the reinstall?

Playback Timing Master is the setting that tells SHS what audio driver to use for playback, and which device to use.
Record Timing Master is the setting that tells SHS what device to listen to while recording.
They may be called 'Playback Device' and 'Recording Device' in the newer software.
I hate when they change the names of stuff.

did you restart after installing the behringer ASIO driver?
