So,

 

when I start up PlayIW4M I get a black screen and a sound, its not an error sound, Atleast I dont think so.

When I tab out I can't find any kind of error.

 

Please help?

Download .Net FrameWork 4

 

 

Also, update your drivers.

When you Alt+Tab what can you see? copy the last few logs on the IW4M console and past them here.

Also you might want to disble your Windows Firewall as when you run IW4M for the first time it would ask to make a exception to Windows Firewall which generally has a similar effect as you stated...

It isnt a .Net Framework problem..

You're most probably missing iw_22 and iw_23

Also try to delete m2demo and caches.xml and run LaunchIW4M.exe

 

by the way.. have you run aiw/alterrev on the same installation before?
