Not to notch up an older thread, but......thanks for the update. I was going to re-download YIM, but it seems they have discontinued the PC version altogether (the last version released was 11.5). They now force access from Yahoo Mail, and for login, either via your existing Yahoo/Mail account, or (should you not have a Y! account) Facebook Twitter, and so on.....and require the phone number for validation.

(Damn, I'm OLD!)
On an off-topic but related note. I'm surprised the forum software hasn't been updated yet to reflect that MSN is no longer MSN, but rather, Skype, as of Windows 10. Though since Skype also takes old Hotmail and current Outlook emails along with its own Skype handles (I can use either my old Hotmail/MSN account or Skype one to log on), I suppose it still makes some sense to leave that as-is for now.
Thanks also to those who suggested alternatives. Maybe I should try Trillian, just to get at old accounts and notify anyone interested in IM play yet (from here or other sites) that still are interested.
EDIT: Thanks to whomever suggested Trillian. Why didn't I use this 10-15 years ago? Now I can restore all my IM contacts here. Not surprised they don't have access to MSN, as that's now Skype, nor any of the newer-fangled 'app' based IMs like Snapchat, Kik and so on....those require accounts for 'app stores' and also phone numbers (which are your 'IP address' in a way). Not a loss.
