I'm not sure if anyone would be able to help about this, but I keep getting this very irritating problem when running the Blue Shift High Definition Pack. I bought Blue Shift when it first came out. I then installed the High Definition Pack and for a while I was very happy. Then one day I had to reinstall HL and when I played it again the High Definition Pack wasn't working. I reinstalled the Pack again but still nothing has happened. I've tried installing the original content and then reinstalling the Pack but it still doesn't work. Could anyone help please? I've had this problem for ages and it's getting very frustrating!
Thanks. :
