I'm unable to get the Central Maven repo index. I'm running Netbeans 7.0.1 and have tried rebooting my PC, rebooting Netbeans 4 times and [alternate mirrors](http://docs.codehaus.org/display/MAVENUSER/Mirrors+Repositories). It sits at 0% and never goes anywhere and never throws an error. I'm unsure what to try or what to investigate to try to determine the problem.
