It sounds like your patch to 1.4b was not successful. See this post/thread:

You will probably have to reinstall and patch again. Make sure you have the right patch. There are four different versions depending on whether you have the DVD or download version of SH3 and Nationality (American/European).
Since you have to reinstall anyway, I would strongly suggest using GWX instead of GW1.1. GWX is the "next generation" of GW1.1 and has many more fixes and features. Check out the manual here:

See the GWX homepage for the files you need. Don't forget the 1.02 patch if you do:
