Scratch

Sometime between 4:00 AM and 6:45 AM I lost the ability to view projects online.  The Java screen comes up but no project appears.  Instead, I get an error.  I am running IE 7.06 on Vista Home Premium.  I am having this problem on two separate computers.  The details of the Java error are here:
