I have San Andreas Mod Installer 1.1 of SAMI but i can't install some mods like weapons 
it appears 
NOTE:.....If it's a mod other than a vehicle then it needs to have a script file created for it before it can be installed with SAMI 
what it means?

it appears 
ERROR 206:Could not obtain update file information fron the sami . text file.
