Got it loaded, finally!

I left it out in the dark bathroom for 1 hour while heating the room up.

The film was still pretty curly and impossible to deal with, but as Crashbox said, trough manually dragging the film almost a whole round and then coaxing it in with very small movements, I was able to spool the film up.

The film slipped several times while i dragged the film round for the first round and also while twisting the spool to feed the film in, so I had to poke it back into the reel several times.

Easy does it.

Now it's going to be interesting to see how much damage my sossage-fingers managed to make while I messed around with it
Thank you all for useful replies ^^
