Üdvözlünk a GTA5-Mods.com-on

I did exactly what stood in the install-discription. But everytime I start the game, it crashes...
Any idea, what I might do wrong? THX

I tried everything I coul`d, but I can`t figure out, what I`m doing wrong.

I installed SriptHookV
I installed SprictHookVdotNet
I installed NetFrameworkt 4.5
and all the redistributables.

I extracted the spg beta 0,5 and putted the scripts folder into the gta5 main folder
also I put the .dll into the main folder.

When I start the game i`m getting this message every time:

----- Begin Exception -----

Seriously, I have no idea, what I´m doing wrong.
I would be very thankfull, if anyone coul`d help me!

(please excuse my bad english)
