Not being quite sure what that means, this may or may not help (and it won't hurt). With a strong carrier network signal (e.g., not merely WiFi), I suggest the following steps, in order, even if they seem redundant to what you have already tried (steps 1 and 2 each should result in a message coming to your BB...please wait for that before proceeding to the next step):

1) Register HRT

  • KB00510 How to register a BlackBerry smartphone with the wireless network
  • Please wait for one "registration" message to arrive to your Messages app

2) Resend Service Books

  • KB02830 Send the service books for the BlackBerry Internet Service
  • Please wait for "Activation" Messages, one per already configured email account, to arrive in your Messages. If you have no already configured email accounts, please wait 1 hour.

3) Reboot

  • With power ON, remove the back cover and pull out the battery. Wait about a minute then replace the battery and cover. Power up and wait patiently through the long reboot -- ~5 minutes.
  • See if things have returned to good operation. Like all computing devices, BB's suffer from memory leaks and such...with a hard reboot being the best cure.

 

If that doesn't help, then here is a KB that discusses that error:

  • KB32439 Error 40721: No Cached Credentials appears when accessing BlackBerry App World

Hopefully it contains something useful! There also are multiple existing threads on this site that discuss that exact error...your review of those might prove useful, and a search of this site, using the error message, error code, or symptom, should reveal all applicable existing threads to you.

Good luck and let us know!
