thank you so much, I can't see how I made such a stupid mistake, I've since corrected it however and it seems to have had no effect on getting the pack to work straight form the launcher. I'll try to get it working again tomorrow but for now I'm quite tired of this and I'm going to take a break. Thank you so much for all of your help. Also something else I noticed, I don't think the pack int that download link actually had mods in it. I suppose I'll figure it out eventually. Again thank you so much for your help. Ta'.
