BB 8830 Error 06 Connection Problem

I'm running a Blackberry 8830. I've run EQO for a couple of weeks with no problems. All of a sudden I am getting an Error 06 - Exception Code: java.lang.NullPointerException error. I tried to reload EQO, but same results. I tried other Java apps, but everything works fine. I've powered the unit down and back up, but still no luck. I have tried switching the TCP/IP setting, and also cycling the radio (as suggested in other threads), but no luck. I haven't loaded any new applications, so I can't think of anything that I could've done to corrupt EQO. Any ideas how I can get it to work again? Thanks! BTW -- great app!
