2 Macs, 1 iCal - Not syncing

Question

I am at a loss. I've had to reset my .mac sync a number of times (had problems with iDisk and key chain). All is working except iCal. My home iCal doesn't keep updated to my work one. I have unauthorised my macs several times (and delted out .Mac stuff). Deleted ~/library/calendar and /app support/ical. Try and sync with a .mac overwrite but get a message that there are inconsistencies, reset from iCal. I have reset from my work iCal but home just won't do anything. I am stuck as to what to do.
Anypone got any ideas?
Many thanks,
Frank.

Used the terminal command to reset syncservices.
