Cannot log in to extension warehouse

I am unable to log in to extension warehouse.

If I try from within Sketch Up, nothing happens (but extension manager does open when I click that).
If I try in my browser, when I go through the sign in, I am returned to the start page of extension warehouse, where I am not signed in.

This has never happened before.
Please help!

I was watching some internal messages about extension warehouse problems. It looks like it was fixed about 40 minutes ago. Are you still having problems?

Thx for follow up Colin.
I CAN sign in online, but not from within sketchup.
