One thing you can try, if you haven't already, is change to a different browser. If that still doesn't help you have a couple of options.
1. Contact the help desk and they can assist you in getting logged in. They can be reached at: 715.475.1111 or https://myhelp.witc.edu/home
2. Stop in the ETC for in-person assistance
