I do not know what is going on. I pay almost $100 to enroll, I have only use it once to download a theology 202 dovument. Now I can not get acces to any other document without paying anothecr large sum. What is the problem? Do I have to pay $100 dolars/ document? If it so so can I get a refund for the other 11 months? Please advise me, My study time is short I cannot waste my time playing financial games. Thank you
