Android Question Error to publish new version apk in Android Market. Certficate Signed

[netsistemas]

I buy a new version of B4A
When i compile a new APK all is ok, but when i publish in ANDROID MARKET, (new version), i get this error:
(Spanish)
Error de subida
Has subido un APK firmado con un certificado diferente al de los archivos APK anteriores. Debes usar el mismo certificado. Tus APK están firmados con un certificado digital que incluye la huella digital

[ SHA1: F2:4D:8C:B60:6B:64:3D:AF:xx.xx.xx.xx.etc]
, mientras que el certificado que has utilizado para firmar el APK que has subido tiene la huella digital
[ SHA1: DD:2B:8F:AB:67:57:7C:E5:57:12:xx.xx.xx.xx.etc]

Error to upload
you are upload a APK signed with a diferent certificate.....

How can i get the previous certicate of ba4 or do a solution for this problem?

This is the solution:
When you buy the application for the first time, you create a certificate.
You saved this certificate in some folder. Find a file name: somename.KEYSTORE
You need the password when create this certificate.

Go to, into B4A, tools / private sign key and load this file. (You may be lucky and remember the password.)

thats all. Compile and upload your new version i google play store (https://play.google.com/apps/publish/)

I remember the solution (more information) reading this post:
