Hello. I'm a fairly decent fingerpicker and I've been trying to learn Bert Jansch's Running From Home and I just can't get it down. I'm not sure why but I feel like I have a mental block haha. Any advice on how to get this down?

I've been using this tab http://tabs.ultimate-guitar.com/b/bert_jansch/running_from_home_tab.htm
"The man that hath no music in himself, nor is not moved with concord of sweet sounds, is fit for treasons, stratagems, and spoils. The motions of his spirit are dull as night, and his affections dark as Erebus. Let no such man be trusted."
