gta iv lcpdfr script error

So I recently bought gta iv on steam and wanted to do lcpdfr. I downloaded it and watched and video and I am pretty sure I installed it correctly because some files I didnt download because it would interfere with others so I think I got that down. So I go to gta iv and for some reason my character is invisable since I installed lcpdfr and when I do alt p it says lcpdfr script error. I downloaded lcpdfr like 3 days ago I think so I am not sure if I got the latest lcpdfr becuase I heard there is a lcpdfr 1.0D and I am not sure if I have that installed. so can anyone help make my character appear again and to get lcpdfr working? also I am not very good witih computerers and didnt understand the troubleshooting tips. Thanks in advance.
