Rogerio, I'm sorry but I'm afraid I may have bad news. Based on further analysis of your dump files, 
I think your Windows install is messed up. I sent you the full dump analysis via PM but if you look at the version numbers of your windows DLL's from you will see that they are 6.2.17134. These are from Windows 8 not Windows 10.  On a good Win10 install these dll's should be 10.x...
 
I think somehow when you reinstalled Windows you didn't get a proper install and this is leading to these crashes and problems. I'm honestly not sure how your system is even booting with a mismatch like that.

Never mind disregard my last message - false alarm sorry.
The debugger misreports the windows dll version numbers after loading the dump initially. 
Will keep investigating..

Noel, just to leave here recorded the result of all your work in investigating the problem and interacting with me several times in PM.
 
I had already given up and I was already starting a new odyssey of reinstalling a new Windows 10 and all its myriad of programs and configurations.

But you did not give up and finally managed to find and fix the bug, something that only happened to me, but that was ultimately a bug.
 
So now it's official: it's working! 

Thank you so much for your great effort and perseverance.
 
This is what makes and has made Cakewalk the main brand of DAW in the world. 
 

Wow. In a world with a dearth of caring Noel is a class act.
 
 

good to hear!!

I'm so glad to hear you're back on track, but it left me curious - what was the issue and how was it fixed?
 
Noel - very impressive customer care, great job! :D
