Walmart.com says they're having temporary difficulties.

I have been trying for thee days to register for the WalmartOne site, so I can get my schedule and pay stub to do my taxes. Each time I fill out the form, get the validation number, enter the number and push continue. The error message popping up is that "We are having technical difficulties" Does Walmart know? I live 20 miles from work and can not just pop by to see my schedule. I called the benefit line and 1800 walmart. mst of them did not even know about walmartone. Please help.
