Vista start up very slow

tried to use CFP 3 with my Vista Home Premium but once installed the box takes 7 min to start !!
Only thing I found in Event Log which does not appear when I use another FW is this :

Failed extract of third-party root list from auto update cab at:
with error: A required certificate is not within its validity period
when verifying against the current system clock or the timestamp in the
signed file.

The message is repeated dozens of times until the box is up and running
Maybe it could be helpful

Too bad I can’t use CFP right now, seems a good job you’ve done
