Oh - and the clicking sound is on purpose - it's the extruder stepper motor skipping backwards because there's too much pressure on the filament. It can get up to about 5kg of force (that's a lot - like 100psi inside the nozzle) before skipping backwards. Much more force and you grind away the filament so this "skipping back" is actually a feature.

Support is a week or two behind. They will eventually get back to you although the phone is much more succesful. You can poke around all you want and won't void the warranty just from removing screws and stuff. I think there is a sticker on the heated bed with a warranty warning so don't mess with that without talking to them first.
260C is hot enough to turn PLA and ABS into a gunk that will clog your nozzle. I recommend the "atomic method" to clean it out - that's the easiest thing to do:

What material were you printing? PLA?
If that doesn't work then you can try sticking a hypodermic or acupuncture needle up the nozzle and do atomic method at same time. If *that* doesn't work I'd take it all apart and remove the nozzle/heater assembly and cook all the plastic out with a gas flame. Google the procedure. People have made videos too. read/watch how other people took it all apart before taking the thermocouple out yourself.
