[SOLVED] ReShade installation problem (Garry's mod)

this is my first time using a forum so idk if i'm using it correctly , sorry for this and for my bad english.
I tried to install reshade 3.0 for garry's mod , i followed all the instructions i selected the directx9 and i launched the game but nothing happened (the overlay and the effects did not work)
i re-tried with OpenGL and directx 10 , i re-installed vc-redist and directx, i removed the fps overlay but nothing happened , when i clicked shift + f2 , the "demo playback" (for gmod) popped up .

what am i doing wrong ?
any help pls?

For Garry's mod you need to move the d3d9.dll file the setup tool installed to your game folder into the "bin" folder in the same directory if I remember correctly. Same for the d3d9.ini file. Source engine games tend to need special handling.

thank you very much , now it works perfectly
