Hey Flood,
Thanks for your reply - I actually managed to sort this about 30 mins after posting. I eventually found a (hopefully) reputable place to get the .apk from.
Only painful part was figuring out I needed a pointer app to be able to log in to KSC once I'd installed it all...
Main reason for KSC is I've got the paid version for a year, so didn't fancy using another service while I'm paying for this one!
TLDR - all seems to be working ok now, hello US Netflix! haha
Cheers!
