carole62, I am sorry to hear that your Doubleplay isn't playing nice at all! How long have you actually had the phone? The error message that you are experiencing generally means low memory on the phone and it appears to have impacted the software. Do you have a lot of text messages on the device? What I would suggest at this point is completing a master reset on your device by following http://support.t-mobile.com/docs/DOC-2783 . Hope this helps!
