-> Start IW5M with my Rev25 Patch ("iw5m.dll") And Updated "libnp.dll"
-> Wait till the game loads up properly (Around 10-15s)
what do you mean by wait till the game loads up properly :/ ? , you said start iw5m on step one...
I LITERALLY mean wait 10-15 seconds.
As the game loads up, certain functions (Steam functions) are overwritten by iw5m.dll or libnp.dll... This takes some time to do which is why you need to wait till that happens.
