Backup error results

Running Windows XP Pro SP2, Sun Java 2 SE
v1.4.2_06

I download the v0.9.1 but cannot confirm upgrade since
ABOUT still shows v0.9 ! Suggest changing ABOUT to
reflect actual version including minor patches or build
number...

Next,

Attempted to run FULLSYNC with a simple BACKUP
local C: to firewire external G: job excluding file types

Program executes in window FullSync 0.9, after
processing request Task Decision window pops up with
listing, then select pull-down option EVERYTHING and
click OK results in EXCEPTION popup:

java.io.FileNotFoundException: C:\.\Documents and
Settings\NetworkService\ntuser.dat.LOG (The process
cannot access the file because it is being used by
