Bug:

After the MSN Live install, no sweat, it works, i can log into MSN and have a chat.
Then when I download the Plus add-on and install it the problem arises.
I will start MSN from the start menu (auto start with windows disabled)
So far so good, MSN is running, then I log-in with my UN/PW.
After signing in it takes about 2 seconds, then a pop-up box appears saying:

"Messenger has stopped working"
"Look for a solution online and close the program"
"Close the program".

The last two lines are the options I have.
After removing Messenger Plus Live, my MSN works as it should, no swear again.

I now have MSN running but I really like the features of !Plus.
If neccessary I can reinstall Plus for a moment and get you guys the details of the crash.
This I can remember:

APPCRASH
mssmsngr.exe
.....the rest is numbers and hashes whatever


Help much appreciated,

Same problem for me.. :/
did it work for you ?

Just as a note, I think this might be worthy of looking in to. Another user on the IRC support channel, also with the 64bit version of Vista had the same problem just now.

can you send me an email at mplus-support@patchou.com ? we'll try to work this out together. I'm using Vista x64 myself and I have no issue. Make sure you disabled all your scripts (if any) too.
