Trouble with Microsoft account and Windows 8.1 syncing

I have two PC's running Windows 8.1 Preview that are both having these two problems:

1. Aren't syncing their IE11 favorites and favorites sort order.

2. Stuck syncing the same files with Skydrive. Opening the modern Skydrive app shows the same files in the queue have all been "pending" for the last several days.

I reset all trusted devices on my account and then retrusted both PCs and still have these issues, so I then ran the Microsoft Account troubleshooter and it found these problems with the first PC:

I don't know what the first two errors mean, but the third one is probably because I disabled the Desktop personalization syncing.

I then ran the troubleshooter on PC 2 and got this midway through:

I opened the store (which opened normally) and waited several minutes but nothing happened. So I hit Next on the troubleshooter and it finished with these errors:

Again, I don't know what the first two errors mean, but the third one is probably because I disabled the Desktop personalization syncing.
