Have lost my calendar and contacts!

When I went to Calendar today I get the error message " This folder contains no items and no operation can be performed" Plus it says exactly the same for Contacts. The only thing I have done is change to a PRO licence. Any help out there?

Probably because you have not selected a folder. Click on one of the contact or calendar folders, and see what happens.

If you had saved your calendars and contacts in Local Folders, rather than in a synced folder, if Local Folders are not visible below your other folders, you can enable them by selecting Menu > Settings > General > General > Show Local Folders. Click on Save & Close to save the setting.

Thanks Gary - Went on a wander around, changed some settings back from where I changed them to, and all returned. Not sure what happened but all okay now, thanks.
