mpl is good ^^ ive been using it for a few years and it worked fine but today i just found out that the all the plus buttons r gone, the colors and stuff all don't work, and wen i clicked on file -> plus it said "software not loaded". i clicked on it and a message appeared that sed:

messenger plus live - error detected
an error occured which prevented Messenger Plus Live from loading properly. you can try reinstalling the software or wait for an update to be available.

i nvr got any problems wif mpl before... dunno why my mpl jus disappeared and doesn't work... i alredy reinstalled wlm and mpl and it still doesnt work... help!

edit:

btw i didnt download any smiley central or any clean messenger thingy..

Has anything recently happened to your pc (installs ect) that match the timing of this? Another thing is go to system restore and have a look if anything new has happened?

Start > All programs > Accessories > System tools > System restore

Also look for unsigned drivers.

Have you installed any patches to WLM or add ons? Like Sweet IM or smiley central.
