You might want to consider doing a fresh start and installing the latest version. I did, and I'm running Gotham 13.2 final. It's been flawless.
I had lots of issues when I tried upgrading from older versions. But when I did a fresh start and started from scratch, everything worked perfectly.
You will lose everything though.
