Default organization accidentally deleted on JasperReports

[JULIENANDRES]

Hi everyone,

I'm reaching out to for some help, I'm currently trying JasperSoft Reports Server Pro and during the configuration I wanted to create a new organization and delete the default one. 
Since the removal of the default organization I can't login anymore on Jasper because he ask me to fill out the oganization field on the login page.

Any idea on how I can create an organization without any access ?

Thanks in advance.

Best regards,

I allowed myself to top up this one, any idea ?

Thanks in advance
