The version that GoDaddy has is not current, and can have issues - it has been noted many times on the forum that GoDaddy generally is not a suitable host for YAF forum due to limitations on GoDaddy servers. You can attempt to install latest version yourself.
You would delete the installed files from GoDaddy, upload a copy of fresh from download from CodePlex (yafnet.codeplex.com) and follow the installation instructions inside the ZIP file.
Additionally, if you have problems still, you can post a request in the YAF Jobs forum and a developer or YAF supporter could accept the job and install/setup for you. But keep in mind still, that GoDaddy is known for having issues with the YAF requirements for a server.
