Hello Dutchman101,
first of all, thanks for your reply, I appreciate that! I installed a non modded gta3.img file but I still can't join the server, it's still crashing. After that I downloaded MTADiag and there were some modded files in the GTA folder so I downloaded the original files and replaced them. I tried to join the server but it's still crashing. Here is the pastebin file which MTADiag sent me:
