Question : Log full on my watchguard 750 e firewall

My log files are full on my watchguard firewall.  I've been in contact with the IDIOTS (and I do mean idiots) at watchguard since yesterday and the can't seem to help me.  I'm in a bind I have 19 gigs of free space left and I need to find a way to clear the logs.  The IDiots at watchguard gave me instructions but they are not working and they've left me hanging!
this is what I did:
C:\Documents and Settings\Administrator.HCIBOOKS>cd \program files\watchguard\ws
m10.2\postgresql\bin

C:\Program Files\WatchGuard\wsm10.2\postgresql\bin>psql -U wguser wglog
Password for user wguser:

close this out. I have to deal with this via the registry and then reinstall
