Hi, I cannot access my course assignment through launchpad. When I tried to login into the assignments, it said that my 'free' trial ended on Feb. 19 as I clicked on the 'request free trial', and I had no idea that I was using the free trial version. Now I can't access my assignments. Also when I tried to enter the access code that I bought from last semester, as I am using to access my course assignments from this semester up until now, it said A system error has occurred. Code: 'SystemError'; Message: 'No uses left'. And, when I clicked on 'purchase access', it give me a message saying sorry, there was a problem processing your request. Please try again. I cannot click all three of them. What should I do? Please help. I have also tried to contact the macmillan technical support number and they were saying 'sorry, your call could not be completed'. Please help.
