I'm having trouble with my Windows Address Book. I run Windows XP SP2 on P4 1.6 GHz, 384 MB RAM. I use Sony Ericsson PC Suite to back up the contacts data on my Sony Ericsson W550i to the Windows Address Book. Today after a synchronization completed the report showed that some contacts has failed to update, though others had been updated. After this, it has become impossible to either synchronize with the Address Book or open it.
Trying to open Address Book results in the error message "An error occured while attempting to open the Address Book file." Outlook Express is the only synchronizable application I've installed, so currently it has become impossible for me to back up my contacts data. Other operations such as file transfer remain unaffected. What should I do?
