hello evrybody

me and collegue have finised of developping tizen application 

the application was rejected one time for some errors

but when we finished  of fixing them and republish the application we have gotted this message:

The Author Signature information does not match the information in the tpk (or wgt) file previously registered.
Updates can only be processed with the same Author Signature, so you must re-register an application if you want to use a new Author Signature.
 

what we have to do 

thanks
