yeah, i had messenger 7.0 and messenger plus 3 with stiff plug and when i saw in stuffplug.com that stuffplug doesnt get along messenger 7.5 so i disabled it before install the new version cause the author says he is going to corect it soon, but when i installed it, meseenger started normal but i couldnt open a window conversation, i uninstalled messenger plus and it worked perfectly now, but im scared of reinstalling plus, maybe it wont work again. but ill give it a shot and ill tell you.
well just as i said, it didnt worked, just as i am initiating it i closes itself and mark an error
