I can't Reset My Html Course

i did 33 Percent of the Html Course and then Was Quite Busy with School…Now i wan’t to reset it and Start again when i click Reset Button it Does not Work even when i log out What can i do ?

Dose the course Dashboard part say 0% if it does say 0% the courses were updated also You can report that to the help Desk(if it dose not say 0%)
