OK, in your TOC, select one of the page #s and press Shift-F9. You should see something like:
{PAGEREF _Toc298941567 \h}
If the \h isn't there, that means your TOC has been created without the hyperlink switch for the page #s.

Likewise, if you select the whole TOC and press Shift-F9. You should see something like:
{TOC \h}
If the \h isn't there, that means your TOC has been created without the hyperlink switch for the headings.

If the \h switches are present and hyperlinking isn't working, you've definitely problems with that aspect of the application also.
