"Your account is disabled. Please contact your administrator for details" Error in Zoho Expense

Hi,

  I deleted my organization's admin user account from Zoho Expense which was running on trial expenses to start with new actual expenses. However, when i try to integrate the admin user account in Zoho Invoice to Zoho Expense it shows this error "Your account is disabled. Please contact your administrator for details". Can you please guide me thru this to activate my admin user account for Zoho expense?

Regards,
