Hi
@jboykin - I am assuming that you also clicked on the 'help' icon on the open page. This then brings up 'register' and it should work from there. I see you are working from the 7.1 version - have you installed the 7.4 you said you had purchased WC a second time? If you haven't you need to go to the main home screen, click on account (top right) and scroll down to the active resources. When you see 7.4 download, download. That way you will get the up to date version - not that I think that should make any difference though.
Let me know, sorry you are having problems. You will get sorted, promise!
