ical & isync problems

Hi I'm having issues with isync and/or ical. A few Days ago my ical just wouldn't work. Three hours with Apple support fixed that (the last agent sorted it out in 25 mins:-). I didn't do anything with it for a few days and now isync runs but takes minutes before it will respond to keyboard/mouse input and refuses to sync my phone, With an error that says "No writable calendars found:Before you can synchronize your calendars, you need to open a calendar application that supports synchronization and create at least one writable calendar." I've rest synch history, deleted devices, deleted and added new calenders to no effect. Before I get to Apple perhaps someones had this happen?

The System Messages Log shows the following:

There's other stuff but I've copied what I think is relevant..

Help please?
Thanks!

Hi
I solved it by trashing everything to do with iCal and iSync, reinstalling both, then restoring ~/Library/Application Support/iSync and ~/Library/Application Support/SyncServices from a TimeMachine backup. The key seems to be in what's in ~/Library/Application Support/iSync and ~/Library/Application Support/SyncServices; because iSync and iCal worked fine in another account on the same iMac.

Hope that helps somewhat.

Thanks zeev1269!
I tried your method, but felt lazy and did not want to do any reinstalls. I went back one day in time machine (I knew it worked then), restored and replaced the folders ~/Library/Application Support/iSync and ~/Library/Application Support/SyncServices. Afterwards it worked just as before. Make sure to keep a backup of your calender though in case something goes wrong.
