a way to fix MSN messenger login error 800B0001
my friend JiaNi Huang has experienced a diificulty in MSN messenger login for more than 3 months. I tried to install the latest beta version for her, but that dose not solve the problem, so I looked up the internet and found the following solution, it was originally written in a non-english language, so I post it here, hope it helps.
for Windows user, open the Run from Start menu, then type in things in the following order:
regsvr32 Initpki.dll (this one took about 30 sec to be complete.)
after you done this, you should be able to sign in the MSN Messenger ! ^^
