Hi all, after days of wrestling with this issue I found a simple solution that worked for me and has resulted in all packs being installed correctly without having to edit the directory or search for missing files.
Simply this:
You must install each pack separately and run it before installing the next one: install, load up, run and then close it down BEFORE installing the next pack.
Running after each installation completes the installation as files and directories are still being generated by the initial run process.
If you install everything in one go and then load up the game will have essentially skipped some important steps.
Hope that makes sense and hope it works for all those having issues.
