Hey guys, I’d really need your help!
I bought an IBM machine with Windows XP as the OS. I installed MSN 7.5 and connected to it without any problems. Went to sleep, closed my computer and came back the next day but now it keeps saying ‘‘Error’’. Sometimes it tells me my username is non-existant or I typed the wrong password and sometimes it tells me they can’t connect me to MSN for the moment and to try again later. I have 2 MSN adresses, I tried to connect with my secondary adress and it worked but my main adress is still not working.
So I went and tried to connect with my main adress on my Vista and Windows 10 and everything worked fine so I was wondering what am I doing wrong? Everything was working perfectly fine 2 days ago. If someone could help me out, would be much appreciated. 
(Sorry for my english, I’m french)
