I used to use Yahoo sync for my calendar and contacts. I started using Gmail and synced contacts and calendar using the Blackberry App. I found that I was getting duplicate entries and furthermore, it wasn't working with the today theme I have so I deleted Google Sync and tried to resync using the desktop manager.

Now I'm getting an Intellisync "Unknown Error". I tried re-installing the desktop manager and rebooted my computer but I'm still getting the same error.

Any ideas?
