internet explorer problem??

on my desktop have quite regularly deleted cookies, temporary internet files and history via internet options to save space on computer

on restarting had to doubleclick on ov homepage log in and my username and password are automatically filled in then i can log in

just did wipe of pages on my new laptop for the first time now i can't log in properly

unless i deselect the tick on save my password, then i can use for my session but if i close down computer i'm back to a blank page for login again

any advice please?
