You say ...I am running the latest update of Pro Tools 10
I assume you have updated PT10
Did you uninstall the previous version before updating.You should find the PT uninstaller in your file.
This is what is usually advised. Some dont bother and have no problems.
Not saying this is your problem but thought it worth mentioning.
For now you could try using this...ProTools Pref and Database Helper
