Cannot access Web of Science

hi,

sorry if asking in wrong place but Im new to Endnote. I just purchased Endnote X.0.2 for my wife but  she cannot access when searching for references using Web of science connection (accessed at home). But she said she got no problem when using Endnote in university (same version that i just bought). Do i need to pay to use Web of Science database?

thanks for any help.
