I've got the same "Software not loaded" problem which several others seem to have as well.
I do not use any MSN plugins (other than MsgPlus), I do not have any software such as smiley central.
I did a complete uninstall of both MP!L and WLM, removed both folders from C:\Program Files and then reinstalled first WLM and then MP!L.
I still get the same error message. Is there a more detailed error log somewhere which might help me pinpoint the error, or a way to put MP!L into debug mode or something?
I've been in tech support for many years, and I personally find this error message unhelpful... Hopefully someone can give a better answer than what I checked in the FAQs, and the repeating of the FAQs which seems to be the only answer these threads have had previously.
Software Versions:
Windows XP SP2 (up to date on official MS patches)
Windows Live Messenger 8.0 (Build 8.0.0812.00)
Messenger Plus Live 4.11.0.254
For those who haven't seen what the error looks like...
