The loading screen goes all the way to 'registered' and then program disappears. I've tried every option to fix the files. CRC says it refreshed. I reloaded the executables and finally removed and reinstalled BW10 twice, but it does the same thing. I ran repair on Windows 10 as well. Finally I downloaded the new July ISO file (20 hrs), but that won't even load so I reinstalled from my thumbdrive.
