I couldn't see the IM in game, so i tried a lot of things, and now with all combined it does finally work. For all that have the same prob, here's what i did to make it work (i'm not saying it is the best way nor even a good way to make it work, but it worked for me

)
1)Delete the old IM + the S4IMConfig in your S4 League folder
2)download BOTH c++ packs and install em
3)download and extract the new IM to a folder (i have that folder as a exception in my AV)
4)copy the MSVCR100.dll to the folder where the IM is
5)Start IM BEFORE you start the S4 Launcher
Now it works for me, it might as well help some of you...
