You must use your SketchUcation member's name to try to login: NOT your email address.
Then use the membership's password...
If you have 'forgotten' either of these send a separate email or PM to one of us...
I see the memebership-name associated with your email is 'Blevins64'.
Your password is your own - we can't access it - but we could reset it, if you want...
Gábor is our IT guru...
Let us know...
PS:
You could try deleting your Internet Explorer cache
[ sometimes used by dialogs in SketchUp] in case something got screwed up ! ]
Then restart SketchUp...
