VM Name reported incorrectly by resxtop

I renamed my VCenter VM from VCenter (1) to Vcenter but when useing resxtop in still shows as the old name.  I've looked in the vmx file but can't find where its getting this from.  I use Zenoss to montior my server which has a Package for ESXi which is just using the resxtop utility to get info back.  Anyone know how I can get the name right  I'm using ESXi 4.1 with vSPhere essetinals licensing
