vista64: driver not loaded after updates, testsigning enabled

Hello,
I'm developing a KMDF driver under Vista64.
It has a test certificate, and loads fine if I attach windbg.
This morning (feb 14 2008), the driver is not loaded anymore.
In the device manager, I see "error code 37", which could indicate
a failed driver signature enforcement, if I remember right.
And as I used an early beta of WDK 6001, this was caused by WdfCoInstaller01007.dll: my driver was fine, but the coinstaller could not start.
I tried this:
- disabling signature enforcement with F8 at boot time does not help.
- "bcdedit -set testsigning ON" does not help.
- reinstalling the test certificate on the target machine did not help
I had some Vista security updates automatically installed this morning, maybe this caused the error.
What to do now?
Thanks for caring
