Thanks gents, I've searched all the possible email accounts and Skype only comes up twice, though not to do with logging in and passwords. When I typed the various email addresses into the Skype new password generator, it simply says no!
I have managed to sign in on an old laptop where the password is automatically written (but security screened). I thought that I might be able to 'see' the password by playing around with the Skype preferences, but no luck so far.
If I deleted the Skype on my newer laptop and transferred over the one from the older laptop would the login information remain intact and solve my problem perhaps ? I'd hate to have to set up a new account unless it seems all avenues are closed.
