Enzymind Labs

I haven't been able to solve my problems accessing Enzymind, and severals others can't access it also.

I can access it on a Univ. of Oregon connection, but the following message appears before each page loading:

Note that the details indicate it it a uoregon certificate. I can't access ever on my home account (a Clearwire service), and haven't been able to since early March. The DNS (Domain Name Server) is properly accessed, but the browser is "unable to connect".
