Get BSOD

Haven't had any problems with the latest beta until today, when it BSOD on restarting. I'm not sure exactly when the BSOD happened as I wasn't watching, so it may have been when shutting down, during boot or after reaching the desktop.

As before, the dump refers to spvve.sys. Again this is on my brother's PC, with a single 1GB FAT32 Logon Mounted RAMDisk, which is compressed to only use 12KB on the HDD.

I was using a RAMdisk of 16GB in version 3.4, but in order to freeze the program is in response without
After the uninstall
Error code = c0000098 was re-install version 3.3.3, but when you try to use the image that were available in 3.4
It will be displayed.
Whether there is no way to repair?

I want a button on the feature that allows you to back up only the data that has been updated

New beta (20th of august) works fine, but it still generates system events 11 and 32 at startup on my W8Pro machine.
