You can try doing a /squeenix reload,
if that fails, try going into the wtf\account\yeraccountname\Savedvariables
when you are there, delete all files with squeenix in the name (should be two files)
Doing so will reset all settings for the map addon, upon login in it will be as if you had never used that addon, to unlock the map then simply do /squeenix lock
(Doing /squeenix will give you a complete list of the avalible commands for that addon)
