CursorFX is now available as a beta through Stardock Central. It went public last night.
We are tracking a bug in the upgrade page. When you go to the update page there are several users that have found that the site cannot detect CursorXP on their account. We are fully aware of the issue and are working to correct it. Sorry for the trouble.
As a side note users of CursorXP whom used the switch for turning the cursor on and off it has been changed from crtl+shift+c to ctrl+shift+v.
