Hello, I am new :D So well, my problem is simple and not even having looked at the faq has helped me. I did install some mods (1997 by schumi and 1993 by gp4 central), played them, and then uninstalled them. They both worked well the first time, but when I tried to install them again zaz tools and/or any of its executables didn't work. Neither the version with an installer neither tby jaguarcatalonia - Grand Prix 4
