With those mods, v1.5 is necessary... When you go to install, use your Steam online account, and have it install in a directory other than the "default..." C:\ Program Files (x86) \ Ubisoft (or probably Steam then Ubisoft, whatever). In other words, don't put the game in a Windows "protected" folder. THEBERBSTER has links in his sig, follow the SH4 one to the "Moving Steam" thingie... I'll look for it also, and post an "Edit: " here in this post too... But THEBERBSTER has probably got the best signature as for help...
Edit: Hah! It's #3 on his list!
