Cant log into WD Dashboard

After taking ages to set-up transfering Gb’s of data , added mapped drives on my pc etc. All sorted, except now for some bizare reason i cant log into dashboard. all my mapped drives etc work fine, using the credentials that im putting into dashboard. I have even xterm’ed to the my cloud and ensured the password and user name are correct, yet still cant log into dashboard. it simply respondes saying invalid username or password !!

Any help would be most appreciated.

Delete Cookie-s, I had this twice, this helped me out.

Thanks for the suggestion. I tried that, and even tried a different browser, but still fails to login.
