Ok, managed the download which was pretty torturous but got there!
Then followed this:

Though I had 3.4 installed on my Kindle and chanced it by using the 3 bin files in the 'for 3.2.1 and 3.3 version update'. Which didn't work
Did the update in the Kindle settings and it said there was an error during update, and no dual boot screen after reboot.
Connected to Kindle again and the DK_System folder is where I left it, though one of the the thee bin files that I placed in the root (update_duokan_0b008.bin) is now gone... so I'm thinking a partial install?
Anyway, I think I'll have to call it a day here! Unless there are any words of wisdom?
Thanks again for all the help.
