How long have you been online in FTV since placing your order?
Buycraft will periodically check the server and if it finds you ingame it will attempt to give you the items you purchased. if you're not in-game, it can't do this.- since it doesn't know where to put the stuff.
You should get it within 10 to 15 minutes of being online - check your inventory, maybe it's there but didn't print out the notice, as buycraft is showing me it has processed and given your stuff.
If it's still an issue, I'll try re-pushing the package, if that fails I can manually give you your stuff in-game.
