I am a single user using a 3 year old MacBook Pro, running 10.5.6. I have used both NowX Betas and NowX has ceased to sync through my sync services. I thought I would post and look for some direction before I delete and reinstall.
You'll be more likely to get help if you ask up in the Now X Public Beta forums. This forum is intended for questions about the older Now Up-To-Date and Contact, so I'm not sure how many people familiar with Now X will see your question here.
When you repost, it might help if you can include more details, such as if you see anything in the Activity window when you attempt a sync, whether you've confirmed that the events and contacts have the Sync tag, and whether anything seemingly related appears in the Console logs.
Regards.
