Syncing BB 9900 and Playbook with Laptop

Hi

Both my BlackBerry 9900 and Playbook will no longer sync with my Desktop Software. They both used to do so but the bottom right hand corner of the Desktop Software displays as 'disconnected' even though if I use Windows Explorer I can locate each item on the menu with limited access to certain files.

I'm not sure if there is a conflict since upgrading the OS's of each instrument?

Your assistance would be greatly appreciated as I need to sync my 'Organizer' (Contacts especially)

Thanks

Joseph
