I have a remote computer running Windows 7 64 bit that failed to boot properly after upgrading to 2.2.3-cbt beta.
I performed a system restore and it booted just fine. I installed 2.2.3-cbt beta again, completed an incremental file backup and restarted.
The same thing happened…
I once again restored. I rebooted without issue and installed 2.2.3-cbt beta. The same thing again…
You could remove the cbt driver from boot instead of doing a system restore (there are instructions in the manual). That way Windows (sometimes) saves a system .dmp file of the bluescreen. If you send me that I should perhaps be able to find and fix the issue with the new driver version.
