Unable to open my Dashboard to sync my account

I had a difficulty with billing and my sign-in page didn't come up when I signed into my WPMU DEV account. Therefore, I am unable to open my Dashboard and sync my account. The billing problem has been resolved and they suggested thaT I CONTACT SUPpORT TO HELP ME SIGN INTO MY LIVE ACCOUNT AND get this show on the road. I apologise for the capitilization, typing is not one of my skill sets.
