Take the course on your computer or switch devices. Users tend to have more troubles when they try to take the course on their smart phone or tablet. Try a different browser. Chrome and Firefox are best. Clear your browser cache. Check your internet network. Some networks may have firewalls that prevent the course to play. If you are attempting to access the course at your work, try accessing the course home or at your affiliate instead of from work. Comments 0 comments Article is closed for comments.
