I'm trying to check in for my flight tomorrow. It leaves at 4:50 PM eastern time. It's now 8:15 PM. When I click check-in I get a blank page. Anyone else having issues?

I don't want to call Delta, unless I really need to because I know they must be busy with stranded travelers due to the east coast weather. My issue is probably a trivial one compared to others but I'd like some insight.
