I have a Backflip and just upgraded my DejaOffice to v.1.6.2 through the market. After upgrading to the latest version, I can no longer sync with the PC. After syncing with Android Contacts App, the following message pop'ed up with a "Force Close" button.

"The application DejaOffice (process com.companionlink.clusbsync) has stopped unexpectedly. Please try again."

I can no longer sync my calendar with PC. Is there any way to go back to version 1.5.8? At least I can get my calendar sync'ed to my phone with that version.
