I’ve got a problem with license activation.
If I deactivate the license and restart our application, the call to IsLicenseGenuine actually will reactivate the product.
If you deactivate the license activation server side (by deleting the license activation), or invoke DeactivateLicense(), then IsLicenseGenuine() won’t reactivate the license.
Please check the DeactivateLicense() return code to verify that deactivation was successful. It may have reached deactivation limit.
