that download.microsoft.com has for Windows ME. That should be version 6 SP 1: http://www.microsoft.com/downloads/details.aspx?FamilyID=1e1550cb-5e5d-48f5-b02b-20b602228de6&DisplayLang=en
If that doesn't help, better tell more, such as:
- how did you upgrade
- the exact error message
It might be acceptable for you to start using another email program, like Thunderbird.
I have just updated the operating platform on my 11 year old Vaio from W98 to ME. On completion, all works fine except that I cannot access Outlook Express. Error messages state that the program is not reponding because there is a problem with the DLL file amongst others. As I have 2,500 emails stored on the laptop "somewhere" can anyone help me to make O. Express operate again fully. Many thanks.
