Vista - MSN 9.0 crashes & MSN 8.5 signs-in & crashes in compatabilty mode

As of several days ago, my version on MSN 8.5 wouldn't let me sign in. It
kept saying i had to upgrade to MSN 9.0

So i did. But MSN 9.0 doesnt work. It signs in then i can't see any of my
contacts at all. i can see them sign in but thats it. there is no list. after
about 30 seconds (max) it crashes.

I uninstalled MSN 9.0 and reinstalled MSN 8.1 and then tried MSN 8.5
(putting both into compatability mode, which is meant to make it work),
however they would just sign in and then immediately crash.

Therefore i cannot use any forms of MSN.

Is there anyway to fix this?

if you want to use old version 8.0/8.1/8.5 with msnplus and webcam chatting

it working on XP/VISTA/7 Confirmed 100 percent!!!!!

I had the same problem the days before, my windows live messenger crashes after signing in. I searched for the dozens of
forums and I applied the instructions, unfortunately none of them worked. I tried zapmessenger, deep cleaner, I uninstalled
and reinstalled it dozens of times, hopeless.. I tried registry cleaners, antivirus scanning, antimalware programs, I
installed MSN 8.1 by chaning it version to the latest MSN 9 with resourcehacker ( it worked in a friend's situation) didn't
work too. I read in one of the forums that Acer notebooks have incompatibility with messenger and crash, so I installed Acer
MSN patch, as you can guess it didn't work as in nightmares. I did uninstallation by revo uninstaller, nope... I also read
that Adobe flash player has incompatibility with MSN 9 I upgraded it to the latest version, useless...At last I created a new
computer user session in control panel and I switched on new session, surprizingly it worked. I didn't stop fixing the
problem. I understood that it was neither a driver incompatibility nor a virus problem. I was suspected of registry problem
with my session.
Here is my solution: I scanned my system with System Cleaner 5 at first, then I opened system control then startup manager I
unchecked Adobe's ( also its dlls) entries and others that I was suspected of. I am proudly saying that It worked (: I am
using MSN 9 now. I hope I am helpful, enjoy!
