TSN evaluation kit webUI not working

Hello,

We have recently bought 4 Rapid TSN EK. However, as described in the user guide, after connecting the power and PC the WebUI does not appear as it is supposed to be explained in the user guide. Then from the forum and in the user guide's appendix, I found that one solution is to update the bootloader software. But from the website, I cannot download the software. It is telling me that I am not authorised (see the image) but I have created an account in my analog services.

Can you please help me?
