I have just recently completed the beta signup for the Elder Scrolls Online. However After I hit "Complete Beta Application" the button gets grayed and I remain on the application screen. I haven't received an email about signing up for the beta either. Is this normal or is something going wrong with the application process right now?

It could be many things from a server hiccup to slow internet to java issues to what ever. I suggest you leave the page open and see what happens. If you already closed it, the servers may not accept another app, as yours may be in it.

Someone else had this same problem. Disabling ad blocker worked for them.

I just tried disabling ad blocker to no avail, thanks though.

Another thing to try is a different browser. People seem to have fewer problems using Firefox or Google Chrome than they do with Internet Explorer.

If it still doesn't work, you might want to ask them on https://twitter.com/TESOnline.
