Error signing into MSN Messenger
I installed the latest messenger 7.5 version and had trouble signing in since. I did a quick google search and found this article Messenger help
ended up, I had more Passport devopment scraps from the last project. I had to delete my Passport Identity Client Run-time Library (IDCRL) dll, which probably was pointing at Passport INT, (the Passport MS internal sign-in server). I am guessing the latest Messenger had finally upgraded to use IDCRL sign in instead of their custom gateway protocol that they had in the previous versions
everything worked fine after I cleared out the contents from my
%appdata%\microsoft\identitycrl\*.*
%allusersprofile%\application data\microsoft\identitycrl\*.*
+1 for Passport
