If you still have the *.csj file sent to you by RIM, you can re-use it and follow the code-signing key setup instructions to restore the sigtool.p12 file. If you no longer have the *.csj file, then yes you will need to register again.
Some good news - we have fixed the "Uninstall" process for the WebWorks SDK. It will now ask you to backup a copy of your sigtool.p12 file before proceeding in an effort to reduce this type of confusion.
