Hi, thanks for your help. I have had the bb curve for about 6 months and synched no problem. Then I received a "connection synch error" I also checked the log and it read "Internal Error #4238" I have reset the blackberry as well as done the reset with the battery. After resetting the configuration in the intellisynch I then tried differenting things with the configuration. I can synch with no problems the memo, task, and phone. But when I try to add in thecalendar or synch it by itself, the error returns. Any help would be super appreciated! Thank you
