Hi guys, sorry for the long time between updates. The Smackplayer in the video folder was the one I was replacing, and I have now also replaced the smackplayer in the main folder too. this hasn't helped.
Regarding SmackW32.dll, I cannot find a newer/different version online other than the regular smackw32.dll supplied with the player itself, which seems to be identical to the one supplied with Final Liberation. If I'm wrong, please correct me!
The Fifth Horseman's recommended link works. I can't post the link but, dude, how right you are. This solved my problem immediately. For anyone else who has this issue, the link the fix is above. Just point the installer at the epic40k.exe in your gog directory, and away you go.
