I have upgraded LinkMachine, but I'm still receiving a message stating that my free trial will expire or has expired, or my InstantLinks have disappeared. Why?

If you purchased the $89.95 SEO upgrade, then your account was upgraded to the SEO version of LinkMachine, not the Premium version. InstantLinks are a feature of the LinkMachine Premium upgrade, which your account has not been upgraded to, so when the free trial of the Premium features expired, the InstantLinks no longer appeared on your link pages.

Note that there are 3 upgrade options for LinkMachine:

1) Premium ($89.95)
2) SEO ($89.95)
3) Premium SEO ($149.95) (includes both)

For the features included in each upgrade, see this page.

Right now your account has been upgraded to SEO, so it has that feature set, which does not include InstantLinks. The Premium upgrade can be added under Change Settings, Upgrade LinkMachine, for $59.95. Or, if you intended to get the Premium upgrade rather than the SEO upgrade in the first place, let us know and we can switch it.
