I have the same problem here. I've MSN 6.2.0137 installed on my pc and MSN-Plus 3.25. When I've just installed them everything works fine. But when I close msn & start it again a little bit later, MSN-plus is gone. I've allready seen (CTRL+ALT+DEL) that MSN-plus is running. But I don't see it in my menu in MSN. After a minute or so I get a message from MSN-plus that asks me if it can "recover" MSN-plus. I let it do this and msn-plus appears in my menu. It also says there's a program that's having dificulties with MSN-plus. I use ZoneAlarm Pro but I've always used it, never got any problems. Maybe Norton Antivirus 2005? That's the only new program I use...
Anybody any idea? Maybe a dll that won't load? Allthough it's impossible cause MSN-plus is running... I just don't see it and I can't use it...
Ok, it looks like I've finally solved the problem
I've just uninstalled everything that had anything to do with MSN. So I remove MSN, MSN-plus and everything I could find in the register. Then I removed all the junk I had on my computer. Then a reboot. Reinstalled MSN & MSN-plus and everything worked again like it used to be
