Can't login to Admin. always redirected to login page. Although it worked on another PCs

[Kanary]

Dear experts,

Please help me in this:

I'm trying to login to:
http://kanarywatches.com/prestashop/psadmin

but whenever I login using the correct credentials, it redirects me to:
http://kanarywatches.com/prestashop/psadmin/login.php?redirect=index.php

I tried this on my laptop, and my iPhone but it didn't work.

Astonishingly, It worked just fine at my iPad and my Word PC.

tried to clear cookies and make sure it's enabled. tried all browsers but there is no hope, doesn't work on my laptop.

I need it to work on my laptop to be able to build my store. please use this username and pass and try logging, will it work?

UN: [email protected]
Pass: kanarywatches

Please help me troubleshoot this problem.

Waiting your valuable feedback.

Regards,
Hamouda
