I had to do a clean install and backed up my bookmarks using Backup and .Mac syncing, but now I can see them on the .Mac homepage, but cannot seem to get them back on to my computer...!
I've experienced this as well. I'm currently trying to figure this out too. I think you need to create a new .Mac name for your computer, and then sync. I'm not positive; can anybody please confirm this ASAP? Thanks!
