Update:
LeeG is correct and if you do not see the finish button/tab, there is not much you can do. However I was able to get that finish button by unplugging my PLM for a bit and then re-plugging it back to my outlet.
it may be also coincidence that the link probe also had completed at the same moment. Either way I am able to link again and my TimerLinc was successfully added to my network
Thanks for the info LeeG
