Any thoughts? Also, why would only one of two fresh installs of Ubuntu have this problem? Thanks

If you did a reinstall and used a partition, without reformatting it, or copied it from another computer, you may get a different combination of user name and numeric user id. And StrangeThings™ happen.
When you add a user in Ubuntu they typically are assigned a numeric user id from 1000 and up. If you have more than one user on the same computer, and no centralized login-server, the same user name may end up with another numeric user id in a new or different install, if you create the users in another order.
So after a reinstall you may end up with a home directory with your user name, but some other users numerical id. So even if it has your user name, you can't write to it. The same thing may happen if you copy files and directories between two computers, and don't make sure that they both use exactly the same combination user name / user id.
You can check the user name / user id combination under System | Administration | Users and Groups. Go advanced.
The easy way out is to always use the exact same user names and always add the users in the exact same order on all computers, using the same OS.
