Lost my contacts .. or link to them.

[Tomcat]

Fongo was working fine, no issues and love the app. Until today that is. I had the iPhone updated to IOS 6.1, and now Fongo has no contacts, or has lost its link to them.

Can not see them, in fact its simply says "Loading Contacts..." forever.. when Contacts is pressed.
Nothing in list, search brings up nothing.

Tried roboot, tried power off, even tried uninstall and reinstall of Fongo. Somewhere there is a configuration to allow it to link, no idea where it is or why it is not working. It obviously remembers it even after an uninstall, as it comes back same way. I hope all the IOS uninstalls are not like this and are clean, removing everything the app had in place and starting over!!

At any rate, back to issue. Any ideas on how I can fix this.. without contacts the app is somewhat unworkable. The regular phone still has the contact linkage.

Thanks!!
