Did you review the patches, didnt activate experimental ones ? There are a few patches you dont want to activate, marked by yellow exclamation marks. You probably know this tho
Are those path's valid ? is that file located there ?
How did you patch ? By putting the patcher in the sh5 folder and running it, or by copying the needed files from your sh5 install dir to a seperate folder and installing the bunch as a mod (if last, you sure you copied the right files?) ?
version ?
Just a few things that come to mind .. afaik, you know more about this stuff then me .. so it's probably none of the above :p
