SAP BW Connector Password Change

Hi Everyone, 

I've set a connection from PowerBI desktop to my SAP BW (2.0) but then I had to change my password, and now I cant change it on the PowerBI side.

Every time I try to create a new connection or use the old one, my BW password gets locked because of the attemps to connect, but I can found no prompt for changing it.

is there any way for re-setting the password?

thanks and best regards,

Pablo
