Blackberry Application signing problem

hi i m new to blackberry.

i m developing an app which requires code signing. so i fill the app form and get 3 csi files. as i click on csi files they ask for password and any other things. and i provide all the things. and get successfully registerd with rim. but i m working in eclipse. so as click on Project->BlackBerry->Sign with signature tool. as i click on this there is an error which said unable to launch the signature tool as si开发者_StackOverflow社区gning keys can not be found. and as i click ok it takes me again to registration process.

why this is happening as i already registered with rim.i am not getting this situation please help me.

and as try to register it again it says that your registration attempts are no more.

You need to install the keys. Usually there are instructions in the email containing the keys from RIM, but here an online article that explains to how install them, as well: http://docs.blackberry.com/en/developers/deliverables/20779/Obtain_and_install_signing_keys_1264848_11.jsp

This might happen if you've changed PCs or Reinstalled OS. A set of keys AFAIK are only valid for one single PC. That said, RIM dev support can move those keys to the new PC for you if you ask them.
