License Activation Error 0x80090019

[Bert]

I've been running XP since January with no problems.
Changed to NTFS from FAT yesterday and updated numerous
Critical Updates from MS Update page.

Now, system won't start. After login, I receive "WINDOWS
PRODUCT ACTIVATION - A problem is preventing windows from
accurately checking the license for the computer - ERROR
CODE 0x80090019." The machine then reboots itself,
cycling back to the same problem.

Can begin to start in SAFE MODE but once the YES NO for
SAFE MODE is displayed, either choice locks the system.

I've searched extensively on MS Knowledgebase. Nothing
comes close. I haven't changed the hardware config.

This is the closest thing I could find to your problem:

Perhaps the solution is the same.

If you're still having problems, let me know directly, I had a similar
problem and it's simple to solve.
