tells me a package has been accepted when it hadn't been

I am trying to fix a bug in network-manager. This is the history made short:

1. I uploaded a first instance of my package with version '0.7.0-rc2-ppa1'

     ... then I realized I didn't like the username I had for launchpad. Wanted to change
         miguel-mtelleria to snapy.

2. I removed the package (clicking delete) and changed my username, the URL of my PPA repository
     changed accordingly.

3. I did some upload tries with version name '0.7.0-rc2~ppa' having as result:
                                                                                      ^(note tilde ~ instead of hyphen -)
     Mail from Ubuntu installer Wed, 10 Dec 2008 16:00:08 -0000
     Rejected:
     Signer has no upload rights at all to this distribution.
     Not permitted to upload to the RELEASE pocket in a series in the 'CURRENT' state.

4. I rebuilt a new package but I wanted to have the same version as before '0.7.0-rc2-ppa1' with
     another reject result:

     Mail from Launchpad PPA Wed, 10 Dec 2008 16:10:08 -0000
     Rejected:
     The source network-manager - 0.7.0-rc2-ppa1 is already accepted in ubuntu/intrepid and
     you cannot upload the same version within the same distribution. You have to modify the
     source version and re-upload.

So, is there a way to delete a package and replace it with another build?

The source package can be found here:

     http://mtelleria.com/ppa_package

In the meantime I will increase the version number and try uploading again.

Regards,

         Miguel

 .
   * Packing network-manager 0.7 from new upstream version 0.7.0-rc2
     http://ftp.gnome.org/pub/GNOME/sources/NetworkManager/0.7
 .
   * Should close LP: 259214. Now static settings are well remembered
     during sessions.
 .
   * Note that network-manager-applet needs also to be upgraded to 0.7.0-rc2.
 .
   * Importing the same debian metadata from ubuntu-intrepid main. The

     gcc-4.3 has been dropped off (seems to have been corrected in upstream).
