Üdvözlünk a GTA5-Mods.com-on

I have a big, strange problem! When I arrived to the race arena, all the objects spawn doublely! And I think for that reason I get easily the memory error, and a error message by scripthookdotnet.asi file. If I arrive from another direction not from tunnel, game crash instantly with error(s)!
Three pictures about the problem:

What's wrong? Why this happening?? It is annoying and bizarre a little for me!

Thanks

I have a WIRELESS xbox360 controller. I tried use with this mod, but unsuccessfully... can I handle this? Wireless is supported? Because, I noticed that both players moves by xbox controller... I wanna to ONLY 2nd player use the xbox360 controller, not both of players! Only first player controlled by keyboard and 2nd player controlled by wireless xbox controller.
I tried the 360ce program method, and "depluged", "repluged" with open/close battery box (remove, and put again batteries) but still not working... :(

Any suggestions? Thanks!

I trying these sotions from this website about unblocking. http://superuser.com/questions/38476/this-file-came-from-another-computer-how-can-i-unblock-all-the-files-in-a
I think, I have half success now... this mod still not working, BUT the log throw other errors now.
So, now only this error in log file:
[19:46:39] [DEBUG] Instantiating script 'KillStreak.NET.killstreak' in script domain 'ScriptDomain_9E503C4E' ...

I don't understand, all other .Net dll files is working during game, despite I don't unblock dlls when I download and install these mods...
Perhaps other programing method in these dlls?
Any other/new suggestions?

@qiangqiang101
Yep, I disabled these, but still no difference... :/

@qiangqiang101
I unblocked the dll and checked "run as admin" on gta5.exe and restarted my computer, but still not working... :/ strange, but all other .dll mods work, BEFORE unblocking too...
But your mod still not working ...
What is "Mathematica"? I tried to google it: it is a computational software program used in mathematical, many scientific, computing fields... What has to do with this game..?

@qiangqiang101
I already have these microsoft downloads because all other .Net mods is working. but KillingSpree don't...
Yes, I extracted Killstreak folder too to Scripts folder.
This is last log about the KillStreak.NET: (my OS is hungarian, but I tried translate to english.)
[20:40:28] [ERROR] Failed to load assembly 'KillStreak.NET.dll':

This mod dont works for me. :(
Accurately, I think it works in theory because the KillStreak_Sav.xml file has been created during the game but nothing happens when I trying shoot random peds. No subtitles, no sound, nothing...
What is wrong?
The ScriptHookV and ScriptHookVDotNet is the newest.
Any idea? Thanks.
